W3C Publishes Linked Data Platform Best Practices and Guidelines

Photo of Arnaud Le Hors presenting the LDP at SemTechBiz 2014The W3C’s Linked Data Platform (LDP) Working Group has published a document outlining best practices and guidelines for implementing Linked Data Platform servers and clients. The document was edited by Cody Burleson, Base22, and Miguel Esteban Gutiérrez and Nandana Mihindukulasooriya of the Ontology Engineering Group, Universidad Politécnica de Madrid.

For those new to LDP, SemanticWeb.com has recently published the following materials:

WEBINAR: “Getting Started with the Linked Data Platform (LDP)” with LDP Working Group Chair, Arnaud Le Hors, IBM (pictured above presenting LDP work at the SemTechBiz conference last week).

ARTICLE: “Introduction to: Linked Data Platform” by Cody Burleson, Base 22

Those ready to dive into the nuts and bolts of the document will find detailed guidance on topics such as:

  • Predicate URIs
  • Use of relative URIs
  • Hierarchy and container URIs
  • Working with fragments
  • Working with standard datatypes
  • Representing relationships between resources
  • Finding established vocabularies

…and much more. See the full document at http://www.w3.org/TR/ldp-bp/

SemanticWeb.com congratulates the Working Group on this step and looks forward to reporting on use cases and implementations of LDP.

PhUSE and CDISC Announce Draft RDF Representation of Existing CDISC Data Standards

phuse

Silver Spring, MD (PRWEB) October 30, 2013 — PhUSE and CDISC are happy to announce the completion of Phase I of the FDA/PhUSE Semantic Technology Working Group Project. The PhUSE Semantic Technology Working Group aims to investigate how formal semantic standards can support the clinical and non-clinical trial data life cycle from protocol to submission. This deliverable includes a draft set of existing CDISC standards represented in RDF. Read more

LoC Uses Linked Data and RDF for New Bibliographic Framework

The Library of Congress is working on a bibliographic framework for the digital age. According to the article, “The new bibliographic framework project will be focused on the Web environment, Linked Data principles and mechanisms, and the Resource Description Framework (RDF) as a basic data model.  The protocols and ideas behind Linked Data are natural exchange mechanisms for the Web that have found substantial resonance even beyond the cultural heritage sector.  Likewise, it is expected that the use of RDF and other W3C (World Wide Web Consortium) developments will enable the integration of library data and other cultural heritage data on the Web for more expansive user access to information.” Read more

7 New Web Service Specifications from the W3C

The W3C’s Web Services Resource Access Working Group has called for the implementation of seven new web service specifications. According to a brief release, the group “invites implementation of seven Candidate Recommendations for Web Services: Enumeration (WS-Enumeration), Event Descriptions (WS-EventDescriptions), Eventing (WS-Eventing), Fragment (WS-Fragment), Metadata Exchange (WS-MetadataExchange), SOAP Assertions (WS-SOAPAssertions), and Transfer (WS-Transfer).” Read more

RDF 2 or RDF 1.0.1?

The RDF2 Working Group met face-to-face in Amsterdam last week, and Guus Schreiber (who serves as co-chair of the group with David Wood) has just posted about some of the highlights. Schreiber said, “The results of the [Working Group] are not likely to shake the Web world, but will hopefully contribute significantly to enhanced and widespread effective use of Semantic Web technology.”

Sandro Hawke, also in attendance at the Working Group, wrote down his thoughts in a blog post: “18 months ago, when Ivan Herman and I began to plan a new RDF Working Group, I posted my RDF 2 Wishlist. Some people complained that the Semantic Web was not ready for anything different; it was still getting used to RDF 1. I clarified that ‘RDF 2’ would be backward compatible and not break existing systems, just like ‘HTML 5’ isn’t breaking the existing Web. Still, some people preferred the term ‘RDF 1.1’.” Read more

W3C Publishes Two Last Call Working Drafts on RDFa

The W3C RDFa Working Group “has published Last Call Working Drafts of RDFa Core 1.1 and XHTML+RDFa 1.1.” The release states, “The current Web is primarily made up of an enormous number of documents that have been created using HTML. These documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience.” Read more

Five Updated SPARQL 1.1 Drafts

The W3C SPARQL Working Group has published updated drafts of the following SPARQL 1.1 documents.

The current plans of the Working Group are to publish the so called “Last Call” Working Draft around the end of the year.

Public W3C Questionnaire on RDF Evolution

As has been reported earlier, W3C held an “RDF Next Steps” workshop in June 2010 and has published the Report of the Workshop in early July. That workshop discussed the possibility of an RDF Working Group. The overall goal would be to extend RDF to include some of the features that the community has identified as both desirable and important for interoperability based on experience with the 2004 version of the standard, but without having a negative effect on existing deployment efforts.

The Workshop has listed a number of work items that might be of interest for such a Working Group, and has also conducted an informal poll as for the relative priority of those items (with links to the detailed description of the items themselves). As a next step, a public questionnaire has been created listing, essentially, those items (although some of them have been regrouped for a better readability). The goal of the questionnaire is to poll the Web community at large so that the upcoming charter would reflect the real needs for the years to come.

So… if you are interested in the evolution of RDF, here is the chance to make your opinion heard. All the results of the questionnaire will be public. The questionnaire will stay open until the 13th of September.

Rule Interchange Format (RIF) Advances to W3C Proposed Recommendation

The Rule Interchange Format (RIF) Working Group has published six Proposed Recommendations. Together, they allow systems using a variety of rule languages and rule-based technologies to interoperate with each other and with Semantic Web technologies.

Three of the drafts define XML formats with formal semantics for storing and transmitting rules:

The other drafts:

The group has also published a new version of RIF Test Cases, and three other Working Drafts: RIF Overview, RIF Combination with XML data and OWL 2 RL in RIF.

RIF implementation information is available. Review comments are welcome until 8 June.

RIF Production Rules Dialect Revised; Last Call for Comments

During the implementation phase of the Rule Interchange Format (RIF), the Working Group discovered a problem with the design of the Production Rules Dialect. This problem is addressed with a new Last Call Working Draft that changes the way actions are handled to more closely match existing production rule engines. Please send comments and RIF implementation reports to public-rif-comments@w3.org.
