The Linked Media Framework is an easy-to-set-up server application that bundles central Semantic Web technologies to offer advanced services. The Linked Media Framework consists of LMF Core and LMF Modules. The core component of the Linked Media Framework is a Linked Data Server that allows you 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. Its 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, work is proceeding on a proper specification and extension of Semantic Search and SPARQL endpoint for Linked Data servers.
Pax Exam is a tool to ease testing OSGi frameworks and applications. It provides a simple to set up integration test framework for OSGi. You can safely run your tests on a local OSGi framework. It has dozens of supported OSGi framework configurations. You can execute and debug a chunk of code inside your OSGi-based application.
Pixy is a declarative graph query language that works on any Blueprints-compatible graph database. The Blueprints API provides a common interface to over a dozen graph databases, including Neo4J, Titan, Infinite Graph, OrientDB, DEX, and Bitsy. Pixy enables complex pattern matching and logic programming on graph databases by translating PROLOG-style rules and goals to Gremlin pipelines that represent graph traversal operations. Queries in Pixy can also be seemlessly integrated into Gremlin expressions. The combination of Pixy and Gremlin gives the programmer the full power of two graph querying paradigms, viz. graph pattern matching and graph traversal.
RMI WebSocket provides a library for remote method invocations between a browser and a Jetty Web Server using the HTML5 WebSocket. The idea is to enable tight method-level integration between the user interface and the server so that patterns such as MVP (Model-View-Presenter) can be applied in a Web environment. The method-level communications between the browser code and the server code allows the developer to think about the Web page and server-side components as objects in a UML world. Details such as the over-the-wire protocols in WebSockets are abstracted away in the process.
SpiderDB is a lightweight database schema crawler library developed using Java. It is a simple library that can be used to Crawler the underlying schema of a database and return POJO objects, which makes it very easy to use. This library takes care of all the differences among the various database management systems, and makes application code free from the DBMS differences.You keep using same POJOs even if you change the underlying DBMS.
Tranche is file storage and dissemination software. Designed and built with scientists and researchers in mind, Tranche can handle very large data sets, is secure and scalable, and all data sets are citable in scientific journals. Features include a fully decentralized architecture, support for very large files, very long-term file persistence/preservation, file immutability/integrity, provenance, encryption, licensing, versioning, and citability.
