JahiaOne - Semantic Web with Jahia
1 like1,579 views
The document discusses the evolution from Web 2.0 to Web 3.0, emphasizing the need for semantic web technologies to overcome limitations of current systems. It presents Jahia as a suitable content management system for integrating semantic properties and linked data. The authors advocate for structured data publishing to enhance search engine optimization, data interoperability, and the overall effectiveness of web applications.
![Failures of Web 2.0
All the databases and APIs are in “silo” searches are limited
Results are documents, not objects
Are my results up to date and reliable ?
Example : Renault : Too many combinations when you want to buy a car : more than 10^20

![Conclusion
“If you’re not paying for it, you are the product” [1]
Semantic Web is going to be imposed by internet giants because they need
it to know you better
Make the first step to enrich your data, don’t miss the train !
Jahia 7 catches it :
– External data provider
– Quality, extendable editor

JahiaOne - Semantic Web with Jahia
- 1. SEMANTIC WEB WITH JAHIA February 2014 www.sigma.fr
- 2. SUMMARY • WHY ? • Background • Web 2.0 is not enough • WHAT ? • Definitions • It’s real • HOW ? • JAHIA fits • Integration www.sigma.fr
- 3. WHY ? • Background • Web 2.0 is not enough www.sigma.fr
- 4. Background : who we are ? Thomas Delerm and Adrien Di Mascio from Logilab will explain the interest of web semantics in modern web applications for the best use of your data. They’ll give the recipes that make Jahia an appropriate CMS for the semantic and linked data web, a.k.a. "web 3.0" Adrien DI MASCIO - Semantic Web Director Company : Logilab Thomas DELERM - Web Architect Company : SIGMA Worked in cell and IPTV content startups www.sigma.fr
- 5. How the web evolved Web « 1 » was about documents and links Web « 2.0 » is about social and users https://web.archive.org/web/19991116151216/http://www4.yahoo.com/ www.sigma.fr
- 6. WHY ? • Background • Web 2.0 is not enough www.sigma.fr
- 7. Failures of Web 2.0 All the databases and APIs are in “silo” searches are limited Results are documents, not objects Are my results up to date and reliable ? Example : Renault : Too many combinations when you want to buy a car : more than 10^20 [1] [1] http://www.semweb.pro/talk/2474 www.sigma.fr
- 8. Failures of Web 2.0 Web 2.0 is far from perfect : User tag – Different orthography – Different meanings for the same orthography (Hollande) – No relationships between tags You cannot (in one request) answer complex queries like “List on my website 10 products whose producer is Samsung and price under $50” www.sigma.fr
- 9. We have a solution There is always a technical evolution – From PC to Web : WWW and links – From Web to Web 2.0 : AJAX (dynamic web sites) – From Web 2.0 to Web 3.0 : Semantic properties and Linked data So let’s learn what the semantic web is ! www.sigma.fr
- 10. WHAT ? • Definitions • It’s real www.sigma.fr
- 11. Semantic Web – (Anti)definitions Today, Semantic Web is not: Magic Natural Language Processing Image Automatic Processing A new protocol It's a worldwide network of data built upon a set of interoperable standards that use URLs to identify data and link them together. www.sigma.fr
- 12. No Natural Language Processing A human reads: <h1>Semantic Web</h1> <p>Semantic Web is worldwide network of data invented by <a href="http://w3.org/People/Berners-Lee">Tim Berners Lee</a> in 1994.</p> A machine reads: <h1> ????????????</h1> <p> ?????????????????????????????????????????????????? ?????<a href="http://w3.org/People/BernersLee"> ???????????????</a> ????????</p> www.sigma.fr
- 13. If only ... … The machine could read: SemanticWeb is_a network SemanticWeb was_created_by TimBernersLee SemanticWeb was_created_in 1994 www.sigma.fr
- 14. Annotate your document Use rdfa or schema.org <p itemtype="Concept"> <span itemprop="name">Semantic Web</span> is <span itemprop="description">worldwide network of data</span> invented by <a itemprop="creator" href="http://w3.org/People/Berners-Lee"> Tim Berners Lee</a> in <span="creation_date">1994</span>.</p> www.sigma.fr
- 15. Publish another representation Publish RDF and use HTTP content-negotiation <http://mysite.com/SemanticWeb> a <http://www.w3.org/2004/02/skos/core#Concept>; skos:closeMatch <http://data.bnf.fr/ark:/12148/cb119328992> ; dc:creator <http://w3.org/People/Berners-Lee/> ; dc:date "1994". More familiar with JSON ? Take a look at JSON-LD www.sigma.fr
- 16. Vocabularies, ontologies An ontology is a structured set of terms and concepts. Each term and concept is also identified by a URL There are quite a few standard ontologies for various domains (social interactions, libraries, music, events, etc.) www.sigma.fr
- 17. Make it happen now ! RDF is nice Some database engines store RDF graphs - You can query them with the SPARQL language Standardized by W3C You don't necessarily need to change your technology stack If your data is structured, publishing RDF is easy - Choosing an ontology or a vocabulary can be hard - Make your relational database answer a SPARQL query is hard www.sigma.fr
- 18. WHAT ? • Definitions • It’s real www.sigma.fr
- 19. It's all about data Publishing structured data: Helps search engines Better indexation Better page rank Eases external data integration Importing a CSV file requires a preliminary agreement on its structure Maintaining data is expensive, reuse published data (dbpedia, freebase, geonames) www.sigma.fr
- 21. HOW ? • Jahia fits • Integration www.sigma.fr
- 22. Client case : Bpi One goal : use state-of-the art Semantic Web since they are a library (Bibliothèque Publique d’information) 3 main needs: – Input data easily for contents and within contents – Store data in a safe, RDF-friendly manner – Output data • On every page for SEO (RDFa) • In searches • In exports (RDF) Good news : Jahia fits ! www.sigma.fr
- 23. The choice of Jahia Input : - Jahia allows to define clear content definitions (CND files) with inheritance. - Jahia is content-centric Enrich within contents : CKEditor On contents : contribution or edition (GWT) modes www.sigma.fr
- 24. The choice of Jahia : storage and output Storage : you need a framework than can abstract different sources of data : enter JCR – Unique repository for all content – External data are abstract : LDAP, Files, other DB… Output: – Graph structure + XML format fit for meta data – JSP views can be easily tailored for special export formats www.sigma.fr
- 25. HOW ? • Jahia fits • Integration www.sigma.fr
- 26. Input : CKEditor and categories Make sure text data is stored as plain HTML - Properties file to map schema.org HTML code - In-content schema.org properties Created a CKEditor Plugin Triple categorization of contents –Categories (closed list) –Tags (open) –Authorities (closed – linked with BnF) Next steps –Need for a triple store ? –Categorization through automatic spider browsing ? www.sigma.fr
- 27. Content structure Directories per category The semantic mapping is transparent : no additional field to fill in Properties files to map a field and its semantic exports (Dublin Core, FOAF..) Kind of challenges met – Where to store meta data of a file extend jnt:file – How to create a sub content while creating its parents edit Spring GWT XML www.sigma.fr
- 28. Vocabularies used Page Schema.org OpenGraph Dublin Core FOAF Lists Details on short and long contents No Yes No Yes No Yes No Partial Details : events, IT resource [file] Yes No Yes No Auteurs Place No No Yes Yes In HTML Everywhere Header Header Everywhere Format in HTML RDFa Meta Meta RDFa In RDF Yes Yes, one line per meta Automatic (mapping) Yes, native Contributed By Yes, one line per meta Automatic + Automatic Manual Bpi (mapping) Automatic (mapping) www.sigma.fr
- 29. Output We chose RDFa because more widely used for now (than microdata) Debate : shall enrichment be made manually ? Automatically ? Though a mixed technology ? The field dc:xxx mapping will be used to improve search results “ARK” URIs are used to exchange objects between repositories (internal, Jahia, external like BnF) www.sigma.fr
- 30. Future Free your data ! Put them together Share them between applications and externally Forces you to organize your IT differently www.sigma.fr

Editor's Notes
- #21: 19 July 2013 at Google : Knowledge Graph expansion – More than a quarter of all searches started showing some kind of knwoledge graph after this date20 August 2013 Google Hummingbird foces on conversational and semantic search to try and delivery correct answers to broad meanung questions
- #29: We chose not to output semantics on lists pages on purpose
