Metacat

Fixed bug in metacat where return doctypes were not being properly
back traced. Changed DBQuery.findDocuments() so that it no longer
takes a returndoc array, but instead retrieves the returndoc array
fromthe QUERYSpecification. The QuerySpecification was augmented...

Added ability to process multiple "returndoc" elements in
a pathquery document. Now, any query hit will be back traced to an
associated package if that package is listed in one of the
"returndoctype" elements.

Modifications that change the package handling behavior of metacat. Package
membership is now determined by an identifier being used as either the subject
or object in a triple. One can not request arbitrary returndocs -- only
those types that have package information embedded can be "returndoctype"...

fix in the return of the last revisionid on UPDATE instead of the previous one

this is sql script does the same as the sql script named
xmltables.sql except that this script is to be use to
create the database tables on a Postgresql backend rather
than an Oracle Backend

the foreign-key constraints still need to be fixed

fixed the problem with empy password authentication.
Ldap somehow allows DirContext to be created
when empty password is provided as in our case
instead of comlaining like with wrong password string.
So included a check for empty password in order to reject the login.

as John were testing Metacat on postgres,
he discovered that Connection needs more precise check
whether it is open because of db timing outs.
So used to be:
if ( conn null ) { get new connection from db; }
Now changed to:
if ( conn null || conn.isClosed() ) { get new connection from db; }...

fix to view abstract only when abstractpath parameter was specified

specified the correct param list about the "read" action changes

put exception handler messages when acc# is not in the correct format as:
<sitecode>.<uniqueid>.[<revisionid>]
