Metacat

adding a system to track system metadata documents for dataone

Added initial implementation of getSystemMetadata and its associated REST service. Current implementation is returning a hardcoded system metadata document -- need to look up the real document for each guid and return that.

Added comment about MIME form processing.

Refactored metacat to use dataone-service-api-0.3.0 jar file, with the new JIBX generated types and serialization. Included JIBX runtime jar in metacat to handle serialization and deserialization of SystemMetadata objects. Removed the old API jar file.

Modifications to support the DataONE service API version 0.1.0. For DataONE, the get() and
create() services are partially complete. Several more functions and checks need to be added to
create() before it is viable. This DataONE support is not complete, and the current support breaks the MetacatRestClientTest for the time being (this client will eventually be removed).

Modified ResourceHandler to return error codes in XML format for the get() method.

Modifications to metacat rest service to use the new DataONE CrudService for
get() operation. Minor issue with permissions errors propagating up the
stack, but otherwise this is the first implementation of a full DataONE
method.

Modified ResourceHandler.deleteObject() to take a globally unique id (guid)
as input rather than a metacat-conformant docid. The guid is translated
into a metacat docid which is then used in the handleDelete() call. So now
Metacat supports use of arbitrary identifiers for delete operations, but...

Added support to ResourceHandler to allow the putObject method to use
arbitrary guid strings as input. These strings are examined, and if they
match the Metacat docid format (scope.id.rev), they are used directly. If
the id is a string in another format, a new localId is generated based on...

Added initial support for arbitrary string identifiers in metacat (referred to as a guid). The new identifier table is used to map arbitrary string identifiers to Metacat's current docid format (referred to as the localId). Added a new IdentifierManager class to manage this table, adding new mappings as objects are added to the system. Modified the MetacatTest service to utilize this mapping table to look up a localId from a guid. IdentiferManagerTest is working with these guids now, as is the MetacatTest service get() method, but other parts of the system are unaware of them (e.g., create, update, delete operations are unaware, and no mapping is created when new documents are created). As a consequence, the MetacatRestClientTest is not working (although it also had lots of hardcoded dependencies that need to be fixed as well).
