Redland is a set of C libraries providing a high-level API for the Resource Description Framework (RDF), allowing it to be stored, parsed, serialized, queried, and manipulated. It has an object-based, modular design and comes with detailed reference documentation and examples. Redland supports all RDF vocabularies such as FOAF, RSS 1.0, Dublin Core, DOAP, and OWL, the query languages SPARQL and RDQL, and all RDF syntaxes including Turtle, RDF/XML, RDF/JSON, RSS, Atom, RDFa, and GRDDL.
Tapestry is a rich, component-based object model for developing dynamic, robust, highly interactive Web applications. Applications are constructed in terms of Java objects, methods and properties, instead of URLs and query parameters. It builds and interprets all URLs, dispatching directly to application-specific "listener" methods. It includes complete source code, documentation, tutorials and a complete example J2EE application.
The Apache Open For Business Project is an enterprise automation software project that includes ERP, CRM, E-Business/E-Commerce, SCM, MRP, and CMMS/EAM functions. It is a foundation and starting point for enterprise solutions and can certainly be used out of the box, but is also great for creating specialized applications.
Rachel is a resource loading toolkit for Java Web Start/JNLP. Rachel offers two solutions that make resource loading for Java Web Start/JNLP apps easy again. Solution 1 installs a URL handler for a new protocol called class:// that delivers content from jars identified by a Java class. Solution 2 embeds a multi-threaded ultra-lightweight Web server in your app that serves up content from jars in the Java Web Start application cache. Rachel also works without Java Web Start, although this might be pointless. Examples and user documentation are provided.
Luxor is an open-source XML User Interface Language (XUL) toolkit in Java that lets you build UIs using XML and also includes an ultra light-weight, multi-threaded Web server, a portal engine, and a template engine. It is also Web Start-ready, as everything fits in a jar and requires no loose files.
Cypress is an open-source Cascading Style Sheet (CSS) parser that lets you add well-documented, standardized name/value pairs (a.k.a. CSS style properties) to your own XML markup languages. It supports inline styles so you can add style properties to individual XML tags using the style attribute or external style sheets so that you can store style rules for reuse in separate, XML-free text documents. Cypress supports three forms of selectors to match your XML tags and style rules, that is, element selectors, class selectors, and id selectors.
SPindent (Server Page Indenter) is a JSP/PHP structural validator and indenter. It performs structural compatibility check of inner HTML generated from "parallel" branches of process flow statements such as if/else. It allows for those HTML branches to have different entry and exit HTML stack points, as far as the branches are compatible. This allows for verification and proper indentation of handy workarounds, as well as rusty pyramids. It is based on MixedCC (Mixed Compiler Compiler).
