Metacat

integrated new structured query facility (DBQuery) into the servlet demo (MetaCatServlet)

removed debugging code

fixed QuerySpecification to produce SQL that does UNION or INTERSECT set operations for query group combinations

fixed QuerySpecification to produce SQL that does UNION or INTERSECT set operations for query group combinations

finsihed basic functionality for structured queries based on the DBQuery and QuerySpecification classes

added code to build an index of the paths through the DOM tree to each node in the tree as the node is being inserted

db trigger xml_nodes_before_insert no longer in use

for safe nodeid generation

modified shell scripts to support new parser locations and syntax changes

completed work on creating structured query prototype in DBQuery and QuerySpecification classes

added missed conn.close()

continued work on structured query. Now QuerySpecification generates SQL for a given xml input, and DBQuery uses that SQL to send the query to the db

fixed string broken over two lines

documentation cleanup

minor modifications to fix problems introduced with AccessionNumber module

2 new properties added:
defaultGlobalName=NCEAS
accNumberSeparator=:

docid is varchar2(55)
new table xml_acc_numbers
clear out db trigger xml_documents_before_insert

docid is String

docid is String
docid is generated from AccessionNumber.generate() call

gen acc # in new connection
changing to static methods
include action parameter

continued work on structured query -- now it reads the queryspec xml docuemnt and can digest its contents

continued work on developing structured query functionality using the QuerySpecification class -- incomplete still

minor changes to TextNode

fixed error in pathquery.dtd

added incomplete classes for structured query

added result-set filter to DBSimpleQuery to only return specified document type

added query language dtd and example file

changed getDocID() only to:
return docid;

put checkURLConnection(systemId) before
its register in db or using from the parser

rewrote DBSimpleQuery and associated classes to no longer use Oracle's hierarchichal query syntax -- now this should work with any JDBC compliant backend DB

assign rootnodeid, docid for every node in xml_nodes table by given document

to use single transaction
