| − | = OSLC4J SDK =
| + | |
| − | | + | |
| − | Lyo’s central component is the OSLC4J SDK (Software Development Kit) that helps build REST-based servers and clients, compliant with the OSLC standard.
| + | |
| − | | + | |
| − | The library provides:
| + | |
| − | | + | |
| − | * Annotations that automate the marshaling/unmarshaling of Java objects to/from Linked Data RDF resources ([https://jena.apache.org/ Apache Jena] model).
| + | |
| − | * Annotations that allow servers to publish their RESTful API capabilities, based on the [http://docs.oasis-open.org/oslc-core/oslc-core/v3.0/cs01/part2-discovery/oslc-core-v3.0-cs01-part2-discovery.html OSLC Discovery] approach. This in turn facilitates for clients to discover and use available capabilities.
| + | |
| − | * JAX-RS Providers and utility classes to facilitate the development of REST operations for accessing, creating, updating and deleting RDF resources.
| + | |
| − | | + | |
| − | = Lyo Designer =
| + | |
| − | | + | |
| − | [https://wiki.eclipse.org/Lyo/Lyo_Designer Lyo Designer] is an Eclipse plugin that allows one to graphically model (1) the overall system architecture, (2) the information model of the RDF resources being shared, and (3) the individual services and operations of each Server in the system. The figure below shows the information modelling interface:
| + | |
| − | | + | |
| − | [[File:LyoToolchainModel-SpecificationDiagram.png|center|800px|alt=|caption An example domain specification diagram]]
| + | |
| − | | + | |
| − | Lyo Designer includes a integrated code generator that synthesizes the model into almost-complete OSLC4J-compliant running implementation. The resulting code includes:
| + | |
| − | | + | |
| − | * Java classes with appropriate OSLC4J-annotations to reflect the modelled RDF resource shapes
| + | |
| − | ** This automates the marshaling/unmarshaling of Java instances as Linked Data RDF resources.
| + | |
| − | * JAX-RS Service operations for accessing, updating, creating and deleting RDF resources.
| + | |
| − | ** These operations handle any of the supported formats (turtle, RDF/XML, Json, etc.)
| + | |
| − | ** For debugging purposes, JSP pages are also produced to deliver HTML representations of all RDF resources.
| + | |
| − | * JAX-RS Service operations to completely handle [http://docs.oasis-open.org/oslc-core/oslc-core/v3.0/cs01/part4-delegated-dialogs/oslc-core-v3.0-cs01-part4-delegated-dialogs.html Delegated UI] for both creation and selection dialogs.
| + | |
| − | ** Including the initial generation of basic JSP pages for the html-representation of the dialogs.
| + | |
| − | * JAX-RS Service operations to handle [http://docs.oasis-open.org/oslc-core/oslc-core/v3.0/cs01/part3-resource-preview/oslc-core-v3.0-cs01-part3-resource-preview.html Resource Preview]
| + | |
| − | ** Including the initial generation of basic JSP pages for the html-representation of the resource previews.
| + | |
| − | | + | |
| − | Lyo Designer supports incremental development, where manual changes to the generated code are preserved upon changes to the model, and subsequent code regeneration.
