Als ich mich das letzte mal schlau machte, was es rund um das System zur Beschreibung von Ressourcen Neues gibt, waren die Mikroformate gerade aktuell. D. h., ich habe mich schon lange nicht mehr damit beschäftigt. Unabhängig davon wollte ich mir damals genauer überlegen, wie die RDF-Tripel prädikatenlogisch zu behandeln wären, aber inzwischen hat sich da schon wieder so einiges getan. Jetzt sehe ich mir erst EARL einmal genauer an.
EARL soll dem Austausch von Testergebnissen auf Basis einer hersteller- und plattformunabhängigen Sprache ermöglichen, bzw. liest man in der working draft:

The Evaluation and Report Language (EARL) defines a vocabulary for expressing test results. It enables any person, software application, or organization to assert test results for any test subject tested against any set of criteria. The test subject might be a Web site, an authoring tool, a user agent, or some other entity. The set of criteria may be accessibility guidelines, formal grammars, or other types of quality assurance requirements. Thus, EARL is flexible with regard to the contexts in which it can be applied.

Interessant dazu ist auch die Zeiger (pointer) Methode in RDF, siehe Pointer Methods in RDF 1.0

Auf Semantic Web Activity News finde ich dazu:

The W3C Evaluation and Repair Tools Working Group (ERT WG) has published new or updated a number of RDF vocabularies that are part of the Evaluation and Report Language (EARL). These working drafts include:

• Evaluation and Report Language (EARL) 1.0
• HTTP Vocabulary in RDF 1.0
• Representing Content in RDF 1.0
• Pointer Methods in RDF 1.0

See also the Evaluation and Report Language (EARL) 1.0 Guide.

EARL provides a format for expressing test results, such as those generated by Web accessibility evaluation tools, using a vendor-neutral and platform-independent format. While the review period has ended, ERT WG encourages you to review EARL 1.0 documents and submit any comments. See Call for Review: EARL 1.0 Last Call Working Draft e-mail for more information.

The W3C Semantic Web in Health Care and Life Sciences Interest Group (HCLS) is pleased to announce the publishing of three Interest Group notes by the Scientific Discourse Task Force:

• SWAN/SIOC: Alignment Between the SWAN and SIOC Ontologies
• Semantic Web Applications in Neuromedicine (SWAN) Ontology
• SIOC, SIOC Types and Health Care and Life Sciences

These notes describe how one can use the Semantic Web to express and integrate scientific data from different domains and from heterogeneous services. It is hoped that they will inspire further contributions to the ongoing work of the Health Care and Life Sciences Interest Group and its Scientific Discourse Task Force, as well as inspire those in other domains to exploit the Semantic Web.

Today W3C announces a new version of a standard for representing
knowledge on the Web. OWL 2, part of W3C’s Semantic Web toolkit,
allows people to capture their knowledge about a particular domain
(say, energy or medicine) and then use tools to manage information,
search through it, and learn more from it. As an open standard based
on Web technology, OWL 2 lowers the cost of merging knowledge from
multiple domains. More than a dozen implementations of OWL 2 are
already available. The standard consists of 13 documents, of which 4
are instructional.

Be or not to be maybe a bee, fällt mir zur Web Ontology Language ein, aber ob sich die “Manchester Syntax” nun durchsetzt oder nicht, die Schildkröten Grammatik gefällt mir. Ein Schildkrötendokument ist übrigens eine UNICODE-Zeichenkette in UTF-8.

Besonders genial finde ich, dass “tokens” mit “white space” getrennt werden, weil “Zitat:”

… which would otherwise be (mis-)recognized as one token.

Also, die neueste Entwicklung ist schon genial, ich glaube, die beabsichtigen Wörter mit Leerzeichen zu trennen. Also darauf muss man erst einmal kommen, ich finde das wirklich sensationell.

W3C announces the new RDB2RDF Working Group, whose mission is to standardize a language for mapping relational data and relational database schemas into RDF and OWL, tentatively called the RDB2RDF Mapping Language, R2RML. From the beginning of the deployment of the Semantic Web there has been increasing interest in mapping relational data to the Semantic Web. This is to allow relational data to be combined with other data on the Web, to link semantics directly to relational data and to aid in enterprise data integration. The creation of this Working Group follows the work of a previous W3C Incubator Group in this area. Read the RDB2RDF Working Group Charter

Tecnalia, in Spain, has provided a W3C Semantic Web Case Study on the Aquaring portal on aquatic resources. The portal offers a multilingual semantic search engine, a semantic tag cloud adapted to user context, map, exhibitions, etc. The initial aim was to offer a multilingual and unique access point to a heterogeneous and distributed collection of digital resources. This collection was provided by European expert organizations, keeping in mind the possible future integration into Europeana: the European Digital Library.
