Metacat

When calling SystemMetadata.getObjectFormat(), return the string value of the ObjectFormatIdentifier rather than ObjectFormat.toString() (which no longer returns the fmtid string).

organize imports so that it is clearer what dependencies exist on the D1 jars

Merged in the D1_0_6_2_BRANCH changes that include the transition from ObjectFormat calls to ObjectFormatCache calls.

include GUID column for xml_access and related methods for storing/retrieving access rules

do not use XML files for storing SystemMetadata - use DB tables only.

Modified Metacat to build against the D1_SCHEMA_0_6_1 branch of the dataone schemas by incorporating the 0.6.1-SNAPSHOT version of d1_common and d1_libclient libraries, and refactoring Metacat code references to the d1 schema changed types.

updating CrudServiceTest with better exception handling (more specific) to match refactored CrudService.java class

Cleaned up imports.

Updated D1 libraries to head to eliminate problems with date parsing -- added
Joda jar to support date parsing. Removed hardcoded DN from test file. Now
CrudServiceTest is passing again.

Added a new test method testDeleteDocumentByGUID() to ensure MetacatHandler can delete based on GUID, but fall back to docid if the GUID isn't present. Modified CrudServiceTest and made some private methods public to leverage the D1 REST calls in that library (i.e. create() a doc with a GUID).
