Dear all, following up the discussion of two weeks ago, we are very proud to announce the first release candidate of our Linked Media Framework, implementing the Linked Media ideas (cf. http://code.google.com/p/kiwi/wiki/LinkedMediaPrinciples) that I posted two weeks ago. Currently we included only some of the many suggestions that were on the list, but we are reviewing the others until the final release (scheduled end of June).
The release candidate of our software is available at * http://code.google.com/p/kiwi/. Installation should be straightforward for anyone who is a bit familiar with Java web applications (follow instructions in README file). Short description of the features: ===== The Linked Media Framework is an easy-to-setup server application that bundles central Semantic Web technologies to offer advanced services. The Linked Media Framework consists of LMF Core and LMF Modules. LMF Core -------- The core component of the Linked Media Framework is a Linked Data Server that allows to expose data following the Linked Data Principles. The Linked Data Server implemented as part of the LMF goes beyond the Linked Data principles by extending them with Linked Data Updates and by integrating management of metadata and content and making both accessible in a uniform way. Our extensions are described in more detail in LinkedMediaPrinciples. In addition to the Linked Data Server, the LMF Core also offers a highly configurable Semantic Search service and a SPARQL endpoint. Setting up and using the Semantic Search component is described in SemanticSearch. Accessing the SPARQL endpoint is described in SPARQLEndpoint. Whereas the extension of the Linked Data principles is already conceptually well-described, we are currently still working on a proper specification and extension of Semantic Search and SPARQL endpoint for Linked Data servers. LMF Modules ----------- As extension for the LMF Core, we are working on a number of optional modules that can be used to extend the functionality of the Linked Media Server: * LMF Permissions implements and extends the WebID and WebACL specifications for standards-conforming authentication and access control in the Linked Media Framework. (state: almost completed) * LMF Enhancer offers semantic enhancement of content by analysing textual and media content; the LMF Enhancer will build upon UIMA, Apache Tika, and our own Apache Stanbol framework (state: started) * LMF Media Interlinking will implement support for multimedia interlinking based on the work in the W3C Multimedia Fragments WG and the W3C Multimedia Annotations WG * LMF Reasoner implements a rule-based reasoner that allows to process Datalog-style rules over RDF triples; the LMF Reasoner will be based on the reasoning component developed in the KiWi? project, the predecessor of the LMF (state: planned) * LMF Versioning implements versioning of metadata updates; versioning itself is already carried out by LMF Core, but the management of versions will be carried out by this module (state: started) I hope that many of you will try out our system and maybe we also get some feedback for improvements. The LMF is published as Open Source under the New BSD license, so if you are an experienced developer, feel free to help us in the development ;-) Greetings, Sebastian -- | Dr. Sebastian Schaffert [email protected] | Salzburg Research Forschungsgesellschaft http://www.salzburgresearch.at | Head of Knowledge and Media Technologies Group +43 662 2288 423 | Jakob-Haringer Strasse 5/II | A-5020 Salzburg
