APIs for parsing Link to API4KB Main Page

• Multiple forms of syntax checking
  • RDF/XML, Turtle (for RDF/OWL), ?
• Validation API
  • Parser attempts to determine whether or not the resource is valid per the language selected
  • Parser ensures that input file does not contain invalid characters (the character set is specified in the first line of an XML file)
• Translation API – given a resource in a declared input language, provide an artifact in the target language (or as close as possible given distinctions in expressivity; with logging to say why it couldn't do something, what was lost, if anything, etc. in cases where the content language is different rather than strictly the format)
  • typically batch, stateless
  • can be invoked by CRUD APIs as needed
  • may need state management in cases where the client is not asserting the translation to the KB: if the source is maintained in the KB, then translation could be done on demand – source could be added incrementally, but translation could be executed on the fly and either instantiated in the KB or serialized out per the export capability of the CRUD APIs
• Support for error handling
  • Should not “blow up” due to input validation errors
  • Provide hints / description of error, with some indication of where the issue(s) are
• Need round trip capability
  • Load persistent storage into memory
  • Save to persistent format
    • Should be able to recognize the contents of a SPARQL database and then be able to save its contents to RDF or OWL
• Support for both static (batch) and dynamic (run-time, operational) parsing
