Call for XPL use cases

> Brief summary of ours:
>
> O Implement a digital object repository containing metadata information
> about publications (Fedora: http://www.fedora.info, supported by the
> Kowari triplestore http://www.kowari.org)
> O Provide an OPS service call to automate loading of sets of metadata
> about publications into that repository
> O Provide an OPS service call to translate between source and target
> metadata schemas (XSL translations)
> O Provide a generic OPS service layer interface into the Fedora API
> O Provide a web GUI, implementing a query/search interface, allowing
> users to see items matching their query, view the metadata for these
> items in a metadata schema of their choice, and download a set of
> metadata records, again in a schema of their choice
>
> Any questions, let me know.

> Our ingest process basically works like this:
>
> - Service call receives a directory name as a parameter
> - Produce a list of files in directory
> - iterate through each file
> - query repository (iTQL query, generated in pipeline) to identify if
> file has already been loaded (determines whether it is an update or a
> create; but basically similar processes)
> - inspect the file to determine what schema of metadata is being loaded
> - construct xml document in appropriate format for loading into Fedora
> (FOXML) (containing metadata, identifying source file, identifying
> source metadata schema)
> - make SOAP API call to ingest the document (ie create the Fedora
> object)
>
> The metadata retrieval service process works something like this (we
> only store the source metadata format, translations are done on the fly
> based on request)
>
> - service call receives target metadata format as a parameter
> - query repository to determine what the source metadata format is
> (again, iTQL query created on the fly in a pipeline)
> - identify, from a config file the sequence of XSLT transforms to move
> from the source format to the target format
> - run each of the transforms in turn (we've got a recursive XSLT
> transform-runner utility pipeline)
> - HTTP-serialise the result
>
> The query/search user interface does things like
>
> - construct a search page (field descriptions, text entry boxes) based
> on information in a config file
> - construct an iTQL query based on the parameters the user has entered
> - run the query and display results
> - the display metadata and download metadata stuff uses the metadata
