<p><span style="font-weight: 400;">➡️ Late 2023, </span><span style="font-weight: 400;">the Publications Office of the European Union</span><span style="font-weight: 400;"> <a href="https://twitter.com/CORDIS_EU/status/1726865540143276079">announced on social media</a> </span><span style="font-weight: 400;">the public release of </span><strong><a href="https://cordis.europa.eu/datalab/sparql-endpoint">the new CORDIS SPARQL endpoint</a></strong><span style="font-weight: 400;">.</span></p>
<p><span style="font-weight: 400;">CORDIS, aka « </span><span style="font-weight: 400;">t</span><span style="font-weight: 400;">he Community Research and Development Information Service </span><span style="font-weight: 400;">of</span><span style="font-weight: 400;"> the European Commission</span><span style="font-weight: 400;"> », is « </span><em><a href="https://cordis.europa.eu/about"><span style="font-weight: 400;">the [&#8230;] primary source of results from the projects funded by the EU&rsquo;s framework programmes for research and innovation, from FP1 to Horizon Europe</span></a></em><span style="font-weight: 400;"> ». Described as a « <em>rich and structured public repository with all project information held by the European Commission such as project factsheets, participants, reports, deliverables and links to open-access publications</em> », the CORDIS catalog has also been made available in 6 European languages by Publications Office&rsquo;s editorial team.</span></p>
<p><span style="font-weight: 400;">Cherry on top <img src="https://s.w.org/images/core/emoji/72x72/1f352.png" alt="🍒" class="wp-smiley" style="height: 1em; max-height: 1em;" /> of a whole process, the CORDIS SPARQL endpoint release comes to crown a long-term linked open data project. The aim identifying, acquiring, preserving and providing access to knowledge in a common will to share with the widest public possible a trust-worthy, qualified and structured information (see </span><a href="https://op.europa.eu/webpub/op/annual-management-report-2021/en/"><span style="font-weight: 400;">Publications Office 2021 Annual Management Report</span></a><span style="font-weight: 400;">).</span></p>
<p><span style="font-weight: 400;">In the context of the pandemic (and recent opening of <a href="https://data.europa.eu/en">data.europa.eu</a>, the official portal for European data, as defined in 2017–2025 European Open Data Space strategy), </span><a href="https://data.europa.eu/data/datasets/euroscivoc-the-european-science-vocabulary?locale=en"><span style="font-weight: 400;">the EuroSciVoc taxonomy of fields of science</span></a><span style="font-weight: 400;"> was released April 2020, followed December 2021 by the publishing of </span><a href="https://data.europa.eu/data/datasets/european-research-information-ontology?locale=en"><span style="font-weight: 400;">European research information ontology (EURIO)</span></a><span style="font-weight: 400;"> on the EU Vocabularies website <img src="https://s.w.org/images/core/emoji/72x72/1f310.png" alt="🌐" class="wp-smiley" style="height: 1em; max-height: 1em;" />.</span></p>
<p><span style="font-weight: 400;">As presented at </span><a href="https://op.europa.eu/en/web/endorse-2021/conference"><span style="font-weight: 400;">ENDORSE conference March 2021</span></a><span style="font-weight: 400;">, the redesign of CORDIS data-model in accordance with Semantic Web standards contributed to bring the platform « <strong><em>from acting as a data repository to finally playing an active role as data provider</em></strong> », where EuroSciVoc taxonomy &amp; EURIO ontology both played key roles in the creation of future CORDIS knowledge graph and SPARQL endpoint :</span></p>
<p><span style="font-weight: 400;"><img src="https://s.w.org/images/core/emoji/72x72/1f538.png" alt="🔸" class="wp-smiley" style="height: 1em; max-height: 1em;" /></span><em><span style="font-weight: 400;"> <a href="https://data.europa.eu/data/datasets/euroscivoc-the-european-science-vocabulary?locale=en">EuroSciVoc</a> [&#8230;] is a multilingual, SKOS-XL based taxonomy that represents all the main fields of science that were discovered from the CORDIS content, e.g., project abstracts. It was built starting from the hierarchy of the OECD&rsquo;s Fields of R&amp;D classification (FoRD) as root and extended through a semi-automatic process based on NLP techniques. It contains almost 1 000 categories in 6 languages (English, French, German, Italian, Polish and Spanish) and each category is enriched with relevant keywords extracted from the textual description of CORDIS projects. It is constantly evolving and is available on EU Vocabularies website [&#8230;].</span></em></p>
<p><span style="font-weight: 400;"><img src="https://s.w.org/images/core/emoji/72x72/1f538.png" alt="🔸" class="wp-smiley" style="height: 1em; max-height: 1em;" /></span><em><span style="font-weight: 400;"> In order to transform CORDIS data into Linked Open Data, thus aligning with Semantic Web standards, best practices and tools in industry and public organizations, the need for an ontology emerged. CORDIS created the <a href="https://data.europa.eu/data/datasets/european-research-information-ontology?locale=en">EURIO</a> (European Research Information Ontology) based on data about research projects funded by the EU&rsquo;s framework programmes for research and innovation. EURIO is aligned with EU ontologies such as <a href="https://dcodings.github.io/DINGO/">DINGO</a> and <a href="https://github.com/SPAROntologies/frapo">FRAPO</a> and de facto standard ontologies such as schema.org and the Organization Ontology from W3C. It models projects, their results and actors such as people and organizations, and includes administrative information like funding schemes and grants.</span></em></p>

<p><span style="font-weight: 400;">Now fancy a few SPARQL queries in there ?</span></p>
<p><strong>Follow the SPARQL <img src="https://s.w.org/images/core/emoji/72x72/1f4ab.png" alt="💫" class="wp-smiley" style="height: 1em; max-height: 1em;" /></strong></p>
<p><span style="font-weight: 400;">CORDIS SPARQL endpoint is </span><a href="https://cordis.europa.eu/datalab"><span style="font-weight: 400;">actually made available on CORDIS Datalab</span></a><span style="font-weight: 400;"> (and already referenced in <a href="https://linkedopendata.eu/wiki/The_EU_Knowledge_Graph">EU Knowledge Graph</a> among other European SPARQL endpoints ! <a href="http://tinyurl.com/yn5fsylk">see the query</a> / <a href="http://tinyurl.com/2e8z6y5e">see the results</a>)</span></p>
<p><span style="font-weight: 400;">Here you can access a quick documentation guide to CORDIS Linked Open Data : </span><a href="https://cordis.europa.eu/about/sparql"><span style="font-weight: 400;">https://cordis.europa.eu/about/sparql</span></a><span style="font-weight: 400;">.</span></p>
<p><span style="font-weight: 400;">Let’s have a look at EURIO ontology first : we need to understand it to query CORDIS knowledge graph.</span></p>
<p><span style="font-weight: 400;">As we are told in the guide, the latest version can be downloaded </span><a href="https://op.europa.eu/en/web/eu-vocabularies/dataset/-/resource?uri=http://publications.europa.eu/resource/dataset/eurio"><span style="font-weight: 400;">on EU Vocabularies website</span></a><span style="font-weight: 400;">. When we unzip</span><span style="font-weight: 400;"> the archive we access the whole documentation about EURIO Classes &amp; properties that we need to write our SPARQL queries – and a diagram of </span><span style="font-weight: 400;">main classes and properties</span><span style="font-weight: 400;"> of CORDIS data model : </span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2024/01/EURIO_v2.4.png"><img class="aligncenter size-large wp-image-1669" src="http://blog.sparna.fr/wp-content/uploads/2024/01/EURIO_v2.4-1024x812.png" alt="EURIO_v2.4" width="650" height="515" /></a></p>
<p><span style="font-weight: 400;">At first sight we can observe on the schema 3 main groups of entities :</span></p>
<ul>
<li style="font-weight: 400;"><span style="font-weight: 400;">On the top right, the projects &amp; publications associated, key ressources of CORDIS ;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">On the top left, the fundings &amp; grants materials, on « monetary » side of the project ;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">On the bottom, the organisations &amp; persons implied, with references &amp; coordinates.</span></li>
</ul>
<p><span style="font-weight: 400;">Let’s open </span><a href="https://cordis.europa.eu/datalab/sparql-endpoint"><span style="font-weight: 400;">CORDIS SPARQL endpoint</span></a><span style="font-weight: 400;"> – some easy queries can be run to begin exploring CORDIS knowledge graph.</span></p>
<p><span style="font-weight: 400;">Nb : the data on SPARQL endpoint is a snapshot, but freshest dumps can be found </span><a href="https://data.europa.eu/data/datasets/named-graphs-from-eurio-knowledge-graph?locale=en"><span style="font-weight: 400;">on European data portal</span></a><span style="font-weight: 400;"> !</span></p>
<p><span style="font-weight: 400;">Here a simple one to </span><b>find a list of FundingSchemes with their titles and IDs corresponding to « Horizon 2020 » programme</b><span style="font-weight: 400;"> :</span></p>

<p><strong>As a conclusion&#8230;</strong></p>
<p><span style="font-weight: 400;">According to Science (CORDIS saying !), <a href="https://europa.eu/!vYVHXD">New Year’s resolutions appear difficult to be held</a></span><span style="font-weight: 400;">&#8230; because most of time too ambitious, restrictive or unprecisely formulated : indeed, « </span><span style="font-weight: 400;">the </span><a href="https://cordis.europa.eu/article/id/428767-trending-science-do-this-one-thing-to-keep-your-new-year-s-resolutions-research-says"><span style="font-weight: 400;">effectiveness of resolutions depends on how they are </span><b>framed</b></a><span style="font-weight: 400;">.</span><span style="font-weight: 400;"> »</span></p>
<p><span style="font-weight: 400;">Horizon 2024, let’s suggest a(n RDF ?) well-framed one : may CORDIS SPARQL endpoint initiative be an example for other structures who want to share Linked Open Data !</span></p>

To be short I’m a documentalist, terminologist, old (linked &#8211; open) data maniac &amp; lil’ onto-Padawan and… just came to join Sparna’s team this early January !</span></p>
<p><span style="font-weight: 400;">To inaugurate my first article on Sparna’s blog, let’s share a little feedback of mine today about Sparna’s well-known </span><a href="https://skos-play.sparna.fr/play/"><span style="font-weight: 400;">SKOSPlay!</span></a><span style="font-weight: 400;"> whose 10 years’ birthday is to celebrate this year !</span></p>
<p><span style="font-weight: 400;">10 yo, quite a historic tool ! but more than ever actual in a context where the semantic technologies get front of the scene anew due to growing interest shown by the digital humanities movement to data interoperability projects via the standardized knowledge structuration (Wikipedia-Wikidata projects e.g., as semantic wiki devices), and also due to the last progress of artificial intelligence, now able to processing large amount of data and </span><a href="https://www.epimorphics.com/writing-ontologies-with-chatgpt/"><span style="font-weight: 400;">soon fully leveraging the potential of ontologies and knowledge graphs</span></a><span style="font-weight: 400;">.</span></p>

<p><span style="font-weight: 400;">This said, in a more practical way, semantic web standards are not always easy to manipulate as a professional &#8211; if non-initiate to SPARQL and nor confirmed data scientist, and even when you have got to deal with a simple structured list of terms !</span></p>
<p><span style="font-weight: 400;">Either your data is already SKOS-standardized (great !), there sometimes come to have a gap between normalization step and visualization step that requires a bit more technical IT skills. Either &#8211; most of time &#8211; the common muggle-born is to start with a plain Excel spreadsheet, create a list, add some hierarchy, maybe other scope notes or definitions and&#8230; end far puzzled wondering how to </span><span style="font-weight: 400;">get </span><a href="https://www.w3.org/DesignIssues/diagrams/lod/597992118v2_350x350_Back.jpg"><span style="font-weight: 400;">a 5-star data vocabulary</span></a><span style="font-weight: 400;"> ⭐ !</span></p>

<p><span style="font-weight: 400;">… among other nice and useful developments.</span></p>
<p><span style="font-weight: 400;">But as an Excel aficionada, the one that I prefer is </span><a href="https://skos-play.sparna.fr/play/convert?lang=en"><span style="font-weight: 400;">the Excel-to-RDF converter tool</span></a><span style="font-weight: 400;">.</span></p>
<p><span style="font-weight: 400;">One sheet. One import. One result. Easy-peasy, happy terminologist :))</span></p>
<p><span style="font-weight: 400;">(And you can even keep your custom colors templates and formats !!! </span><span style="font-weight: 400;">🦄</span><span style="font-weight: 400;"> )</span></p>
<p>&nbsp;</p>
<p><strong>Come on &amp; let’s SKOSPlay!</strong></p>
<p><span style="font-weight: 400;">Let&rsquo;s figure out you want to display or construct a small vocabulary you could quickly visualize in a standardized SKOS-structured way :</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image10-2.png"><img class="alignnone size-full wp-image-1607" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image10-2.png" alt="image10-2" width="1657" height="1079" /></a></p>
<p><span style="font-weight: 400;">Now to fit in the SKOS model your data has to follow </span><a href="https://skos-play.sparna.fr/play/excel_test/excel2skos-exemple-1.xlsx"><span style="font-weight: 400;">a particular template</span></a><span style="font-weight: 400;"> you can fullfill by downloading on SKOSPlay! website.</span></p>
<p><span style="font-weight: 400;">First you have to define </span><a href="https://skos-play.sparna.fr/play/convert#excel-file-structure"><span style="font-weight: 400;">the header of the template</span></a><span style="font-weight: 400;"> : the global scheme of your vocabulary, its URI, title and description :</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image12.png"><img class="alignnone size-full wp-image-1575" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image12.png" alt="image12" width="1347" height="189" /></a></p>
<p><span style="font-weight: 400;">Adding the terms of your list (with the URIs)… Here with the “@en” language indication on top of the column </span><a href="https://skos-play.sparna.fr/play/convert#languages"><span style="font-weight: 400;">as I am to create an English-French multilingual vocabulary</span></a><span style="font-weight: 400;"> :</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image15.png"><img class="alignnone size-full wp-image-1578" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image15.png" alt="image15" width="1509" height="1021" /></a></p>
<p><span style="font-weight: 400;">Recreating the arborescent structure through the Excel template (don’t mind my color palette, I always like colouring my Excel sheets to better visualize the info at a glance !).</span></p>
<p><span style="font-weight: 400;">The hierarchical broader-narrower structure is to be recreated </span><a href="https://skos-play.sparna.fr/play/convert#sheet-body"><span style="font-weight: 400;">by adding a “skos:narrower” column</span></a><span style="font-weight: 400;"> (or skos:broader, as you want, with only 1 broader value per line) where you will list the different specific values front of the more generic one (separated by comas). Here I used a PREFIX too in order to shorten my http:// URIs, SKOSPlay! can process them anyway !</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image9.png"><img class="alignnone size-full wp-image-1572" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image9.png" alt="image9" width="1943" height="1431" /></a></p>
<p><span style="font-weight: 400;">Then adding a few notes and other information (multilingual values, skos:notation, any other default properties known in the converter (</span><a href="https://skos-play.sparna.fr/play/convert#prefixes"><span style="font-weight: 400;">see the documentation</span></a><span style="font-weight: 400;">) or different custom elements of yours by adding other PREFIXes :</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image4.png"><img class="alignnone size-full wp-image-1569" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image4.png" alt="image4" width="1999" height="1269" /></a></p>
<p><span style="font-weight: 400;">Your Excel template is ready to go ! quite an easy configuration in my demo here, but SKOSPlay! can also deal with skos:Collections, SKOS-XL and other </span><a href="https://skos-play.sparna.fr/play/convert#advanced-features"><span style="font-weight: 400;">advanced RDF structures</span></a><span style="font-weight: 400;"> : blank nodes, RDF lists, named graphs. And now possible to generate OWL and SHACL files with the converter too !</span></p>
<p><span style="font-weight: 400;">Now it’s time to turn your (finally-not-so-dirty-<img src="https://s.w.org/images/core/emoji/72x72/1f438.png" alt="🐸" class="wp-smiley" style="height: 1em; max-height: 1em;" />) data into a SKOS-charming file. Take your favorite </span><del><span style="font-weight: 400;">magic wand</span></del><span style="font-weight: 400;"> SKOSPlay! </span><a href="https://skos-play.sparna.fr/play/convert"><span style="font-weight: 400;">Excel-to-RDF converter tool</span></a><span style="font-weight: 400;"> and load your Excel file in it (adding some optional parameters if needed).</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image8.png"><img class="alignnone size-full wp-image-1571" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image8.png" alt="image8" width="1601" height="885" /></a></p>
<p><span style="font-weight: 400;">Well done, it’s a wonderful RDF-ized vocabulary file (here in a Turtle format but you have also RDF/XML, N-Triples, N-Quads, N3 and TriG available) :</span></p>
<p><a href="http://blog.sparna.fr/wp-content/uploads/2023/03/image1.png"><img class="alignnone size-full wp-image-1567" src="http://blog.sparna.fr/wp-content/uploads/2023/03/image1.png" alt="image1" width="1617" height="1029" /></a></p>

				<content:encoded><![CDATA[<p style="text-align: justify;">Today I have released a new version of <a href="http://labs.sparna.fr/skos-play" target="_blank">SKOS Play</a> with some major enhancements. With SKOS Play you can generate reports of taxonomies expressed in <a href="http://www.w3.org/TR/2009/REC-skos-reference-20090818/" target="_blank">SKOS</a>; the application leverages semantic technologies (RDF, SPARQL, inference, Linked Data) to read a taxonomy and generate downloadable HTML or PDF documents to list concepts, get a translation table, generate an alphabetical index, a hierarchical tree, or even data visualizations of a thesaurus using the <a href="http://d3js.org" target="_blank">d3js library</a>.</p>
<p style="text-align: justify;"><span id="more-441"></span></p>
<p style="text-align: justify;">I have received some feedback during summer, and I thank everyone that took the time to write and share ideas or report problems. This new version (0.40) brings the following new features and enhancements :</p>
<ul>
<li style="text-align: justify;">2 new visualisations :
<ul>
<li>concept listing : lists all the concepts with all their attributes in a given language; this is close to the existing &laquo;&nbsp;alphabetical index expanded&nbsp;&raquo;, but while the &laquo;&nbsp;alphabetical index&nbsp;&raquo; view is label-oriented (each label is an entry in the list), this one is concept-oriented (each concept is an entry in the list);</li>
<li>language correspondence table : generates a 2-columns table with the translation of each concept in a target language; this allows to review thesaurus translations, and immediately see which concept is missing a prefLabel in a target language;</li>
</ul>
</li>
<li style="text-align: justify;">complete re-engineering of the internal &laquo;&nbsp;display data model&nbsp;&raquo;, allowing to easily add new visualisations in the future;</li>
<li style="text-align: justify;">included the <a href="http://www.reegle.info/glossary" target="_blank">Reegle Thesaurus for clean energy</a> as a thesaurus example;</li>
<li style="text-align: justify;">added the ability to read SKOS data encoded in <a href="http://www.w3.org/TR/rdfa-lite/" target="_blank">RDFa</a> attributes within an HTML page (using the <a href="http://semarglproject.org/" target="_blank">semargl library</a>) (but I am still looking for a good example of this);</li>
<li style="text-align: justify;">enhanced header generation : header now tries to read a dcterms:description or dc:description to include in the header; the concept scheme title is read from skos:prefLabel, dc:title or rdfs:label;</li>
<li style="text-align: justify;">enhanced &laquo;&nbsp;section&nbsp;&raquo; generation in PDF documents : each section now generates a page break;</li>
</ul>
<p>Finally, last but not least, you can install a local version of SKOS Play to work around the 5000 concepts limit on the online server. This is as easy as 1,2,3 (a simple war to deploy on Tomcat) and I wrote a <a href="https://bitbucket.org/tfrancart/sparna/wiki/HowTo-SKOSPlayOnTomcat">simple procedure on how to deploy SKOS Play on Tomcat</a>. Note that I do not garantee that the online version of SKOS Play be always available in the future; hosting and maintaining this free application has a cost; time will tell how the project evolves.</p>
<p>I hope to write more about the application, especially about data integration of the <a href="http://lov.okfn.org/dataset/lov/">LOV</a> taxonomy, _not_ expressed in SKOS, but that you can still feed to SKOS Play &#8211; with some tricks ! &#8211; or about how can Linked Data be leveraged to read thesaurus alignments (by the way, don&rsquo;t forget you can always click a label on the HTML visualizations to navigate the concept URI). More on that in the future. If you like SKOS Play, use it, show it, share it !</p>

				<content:encoded><![CDATA[<p>J&rsquo;ai mis en ligne une <a href="http://sparna.fr/linked-data-demo.html" target="_blank">page de démo</a> (assez cool je crois <img src="https://blog.sparna.fr/wp-includes/images/smilies/simple-smile.png" alt=":-)" class="wp-smiley" style="height: 1em; max-height: 1em;" />  ) pour illustrer l&rsquo;utilisation des données ouvertes pour enrichir une page web ou une notice documentaire. Elle démontre :</p>
<ul>
<li>Quelques cas d&rsquo;usage simple des données du web pour enrichir la navigation : montrer des définitions contextuelles, les traductions d&rsquo;un mot, et générer une partie du contenu de la page automatiquement à partir du linked data; on pourrait en imaginer plein d&rsquo;autres.</li>
<li>Ensuite montrer que cela ne nécessite pas de traitement côté serveur : tout est dans la page web. Du <a class="zem_slink" title="RDFa" href="http://en.wikipedia.org/wiki/RDFa" rel="wikipedia" target="_blank">RDFa</a>, du <a class="zem_slink" title="SPARQL" href="http://en.wikipedia.org/wiki/SPARQL" rel="wikipedia" target="_blank">SPARQL</a>, du <a href="http://code.google.com/p/rdfquery/">rdfquery</a>, un peu de <a class="zem_slink" title="JSON" href="http://en.wikipedia.org/wiki/JSON" rel="wikipedia" target="_blank">JSON</a>, du JQuery et tout roule;</li>
</ul>
<p>(Got avait fait quelque chose de similaire il y a quelque temps sous la forme d&rsquo;un module Drupal, ca s&rsquo;appelait la &laquo;&nbsp;<a href="http://www.lespetitescases.net/amusons-nous-avec-rdfa">knowledge box</a>&laquo;&nbsp;; mais la box est cassée et ne fonctionne plus).</p>
<p>On notera que les données de cette page de démo viennent du <a href="http://fr.dbpedia.org/">DBPedia francophone</a>. Il faudrait encore enrichir cet exemple pour montrer une utilisation des données de plusieurs sources de données différentes à la fois&#8230; ce sera pour un autre dimanche ! Allez <a href="http://sparna.fr/linked-data-demo.html" target="_blank">faire un tour sur la démo</a> et dites-moi ici si vous avez des questions/commentaires, voire des idées ou projets similaires !</p>

				<content:encoded><![CDATA[<p style="text-align: justify;">Dans la <a title="Bénéfices clés des technologies du web de données 1/2 – l’environnement distribué" href="http://blog.sparna.fr/benefices-cles-des-technologies-du-web-de-donnees-12-lenvironnement-distribue/">première partie</a> de cette étude sur les avantages des technologies du web de données &#8211; que je valorise au sein de la société <a href="http://sparna.fr">Sparna</a>, j&rsquo;avais étudié ce qui fait leur essence, leur &laquo;&nbsp;principe actif&nbsp;&raquo;, c&rsquo;est-à-dire les mécanismes de publication de données dans un environnement distribué. Je continue ici l&rsquo;analyse sur deux autres aspects qui font l&rsquo;originalité de ces approches : <strong>l&rsquo;absence de modèle de données</strong> et <strong>les possibilités offertes par le raisonnement</strong>.</p>
<p>&nbsp;</p>
<h2>Le schéma de données, quel schéma de données ?</h2>
<p>&nbsp;</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Facilite les phases de prototypage</span></p>
<p style="text-align: justify;">Dans les approches à base de RDF+SPARQL, on n&rsquo;a pas besoin d&rsquo;avoir un schéma de données pour commencer à travailler. <span class="pullquote">On a juste besoin des données. Le schéma peut venir après.</span> <em>&laquo;&nbsp;Data first, model after&nbsp;&raquo;</em>. C&rsquo;est une approche &laquo;&nbsp;bottom-up&nbsp;&raquo;, là où les SGBD+SQL ont nécessairement une approche &laquo;&nbsp;top-down&nbsp;&raquo; : &laquo;&nbsp;model first, data after&nbsp;&raquo;. Cela permet un <strong>prototypage rapide des projets</strong> : plus besoin d&rsquo;attendre d&rsquo;avoir défini un modèle de base de données avant de faire une première requête.</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Intégration de données hétérogènes</span></p>
<p style="text-align: justify;">Ces absence de schéma, de modèle, dans les bases de données RDF (triplestores) donne la possibilité d&rsquo;y intégrer des données :</p>
<ul style="text-align: justify;">
<li><strong>hétérogènes</strong> : exprimées avec des modèles différents, en ayant ensuite la possibilité de les réconcilier sur un modèle unique si besoin;</li>
<li><strong>incomplètes</strong> : avec des valeurs manquantes, en ayant la possibilité de repérer ces objets anormaux si besoin;</li>
<li><strong>incohérentes</strong> : venant de sources différentes qui donnent des informations contradictoires, en ayant la possibilité de repérer ces incohérences et de les corriger si besoin;</li>
</ul>
<p style="text-align: justify;"><span style="text-decoration: underline;">Une infinité de points de vue</span></p>
<p style="text-align: justify;">Zéro schéma signifie aussi une multiplicité de schémas. Les technologies sémantiques permettent d&rsquo;exprimer les mêmes données suivant plusieurs schémas dans la même base, offrant alors plusieurs &laquo;&nbsp;points de vue&nbsp;&raquo;, plusieurs façons de voir les mêmes données. Et ceci automatiquement avec de l&rsquo;inférence OWL. Chaque application consommant les données pourra alors s&rsquo;appuyer sur le schéma qu&rsquo;elle comprend. <strong>On favorise ainsi l&rsquo;interopérabilité entre applications</strong>. Un exemple ? le standard de représentation <a href="www.w3.org/2004/02/skos/">SKOS</a> permet une représentation simple de systèmes d&rsquo;organisation de connaissances (thesaurus, arbres de classement, &#8230;) , à base de &laquo;&nbsp;Concept&nbsp;&raquo; qui portent des &laquo;&nbsp;prefLabels&nbsp;&raquo; (libellés préférentiels). C&rsquo;est un format d&rsquo;échange commode, mais inadapté à la représentation de bases de connaissances riches, comme une base de personnes. Il est tout à fait possible de dire &laquo;&nbsp;ce que tu appelles une Personne dans ton système je l&rsquo;appelle également un Concept SKOS, et la propriété <em>foaf:name</em> que tu utilises correspond à la propriété <em>skos:prefLabel</em> SKOS&nbsp;&raquo;, pour ainsi obtenir une &laquo;&nbsp;vue&nbsp;&raquo; SKOS d&rsquo;une base de personnes.</p>
<p style="text-align: justify;">Ce faisant, on permet également de <strong>séparer les métadonnées initiales des contenus (riches et compliquées) des catégories de ces contenus pour la diffusion</strong>, en fonction des supports ou des publics (souvent plus simples et liées à l&rsquo;usage). L&rsquo;exemple classique est l&rsquo;hôtel rangé dans une catégorie &laquo;&nbsp;bon marché&nbsp;&raquo; alors que ses métadonnées initiales sont plus complexes : prix par nuit, nombre d&rsquo;étoiles, labels, piscine, etc.</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Flexibilité maximale</span></p>
<p style="text-align: justify;">Le fait que le schéma ne contraigne pas les données donne une <strong>flexibilité et une évolutivité importante au système</strong>. On peut rajouter, supprimer, modifier un attribut ou une classe à la volée. <span class="pullquote">On peut modifier le schéma, sans toucher aux données. On peut même changer de schéma facilement.</span> Prenons un cas d&rsquo;intégration de données : une application intégrant une source de données externe avec ses propres données, et se retrouvant confronté au cas où cette source de données change de format et de modèle :</p>
<ul>
<li style="text-align: justify;">dans le monde du XXème siècle, en SGBD+SQL, confronté à un tel cas on doit 1/ modifier le parsing des données qui ont changé, 2/ modifier les tables du système pour prendre en compte ce nouveau format, 3/ modifier les requêtes de l&rsquo;applicatif.</li>
<li style="text-align: justify;">Dans le monde du XXIème siècle, en RDF+SPARQL : 1/ pas de parsing à modifier (les données arrivent toujours en RDF), 2/ pas de schema à modifier (il n&rsquo;y en a pas) et 3/ il faut toujours modifier les requêtes de l&rsquo;applicatif&#8230; plus qu&rsquo;un 1/3 du travail. Et encore, il est possible, le temps de modifier les requêtes, d&rsquo;ajouter de l&rsquo;inférence pour recréer les données dans l&rsquo;ancien modèle à partir du nouveau, de façon à ce que les requêtes continuent à répondre.</li>
</ul>
<p>&nbsp;</p>
<h2>Le raisonnement, ou les manipulations automatiques des données</h2>
<p style="text-align: justify;"><span style="text-decoration: underline;">Réconciliation</span></p>
<p style="text-align: justify;">Le raisonnement est la capacité des outils RDF à déduire automatiquement de nouvelles informations à partir des informations existantes. Notons bien que ces capacités de raisonnement ne sont ni proposées par tous les outils RDF, ni forcément utiles dans tous les contextes. Elles vont par exemple permettre de <strong>réconcilier les données hétérogènes sur un modèle commun</strong> : &laquo;&nbsp;Ensemble des personnes = ensemble des contacts qui viennent de mon répertoire de téléphone + ensemble de mes contacts dans les réseaux sociaux&nbsp;&raquo;.</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Classification</span></p>
<p style="text-align: justify;">Le même mécanisme est utilisé pour des besoins plus proches de la classification (&laquo;&nbsp;repurposing&nbsp;&raquo; de contenu), pour <strong>définir les ensembles d&rsquo;objets dans des points de vue multiples</strong>, tel qu&rsquo;évoqué plus haut. On peut par exemple avoir d&rsquo;un côté l&rsquo;ensemble des objets &laquo;&nbsp;Hébergements&nbsp;&raquo;, et de l&rsquo;autre l&rsquo;ensemble des objets &laquo;&nbsp;Hôtels pas chers&nbsp;&raquo; défini comme &laquo;&nbsp;l&rsquo;ensemble des objets Hébergements qui sont de type hôtel et ont un prix par nuit inférieur à 60 euros&nbsp;&raquo;. Le deuxième ensemble sera calculé à partir du premier, automatiquement.</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Inférence</span></p>
<p style="text-align: justify;">L&rsquo;inférence permet de <strong>précalculer des liens ou des données qui facilitent l&rsquo;écriture des requêtes et améliorent les temps de réponse</strong>. Le total des buts marqués par une équipe de football dans une compétition est calculé comme la somme de tous les buts marqués par cette équipe dans les matchs de cette compétition. La donnée est calculée une fois, et peut ensuite être présentée directement sur la page de l&rsquo;équipe, il n&rsquo;y a pas de calcul à faire au moment de l&rsquo;affichage (voir <a href="http://news.bbc.co.uk/sport2/hi/football/world_cup_2010/groups_and_teams/team/france">le site de la coupe du monde de la BBC</a>, réalisé à partir des technologies du web de données en utilisant le raisonnement).</p>
<p style="text-align: justify;"><span style="text-decoration: underline;">Consistance</span></p>
<p style="text-align: justify;">L&rsquo;inférence est aussi ce qui permet de contrôler la consistance par rapport au modèle de données. Car si en RDF il est possible de ne pas avoir de schéma, dans les cas où il y en a un, <strong>le moteur d&rsquo;inférence sera capable de déterminer si les données sont consistantes par rapport à ce schéma</strong> ou non.</p>
<h2 style="text-align: justify;">Conclusion&#8230;</h2>
<p style="text-align: justify;">Ce travail d&rsquo;analyse partiel est une synthèse des expériences acquises avec ces technologies, et des lectures spécialisées (le forum <a href="http://answers.semanticweb.com" target="_blank">answers.semanticweb.com</a> contient beaucoup de réponses intéressantes). Il doit permettre de bien <strong>situer les avantages de ces technos pour ne pas en faire une évangélisation aveugle</strong>, et de les utiliser au mieux pour résoudre des problèmes concrets. Il y aurait peut-être d&rsquo;autres avantages à étudier, comme la réutilisation possibles de schémas existants, comme ceux que l&rsquo;on peut trouver dans le <a href="http://lov.okfn.org" target="_blank">LOV</a> (Linked Open Vocabularies).</p>
<p style="text-align: justify;">De plus en plus de projets vont vouloir soit tirer parti de ce qui est publié librement sur le web de données, soit rationnaliser des intégrations d&rsquo;API compliquées, ou encore améliorer leurs chaines de traitement et de diffusion de contenus, ouvrir des données de bases auparavant fermées, aligner des référentiels avec du raisonnement, etc&#8230; tous ces projets peuvent bénéficier d&rsquo;une approche basée sur le web de données.
