Metacat

Merged in substantial changes to DBWriter and associated classes and to
the MetaCatServlet in order to accomodate the new UPDATE and DELETE
functions. The command line tools and the parameters for the
servlet have changed substantially.

Fixed bug in DBWriter using the new SAX2 interface. Turned out it was a bug in xerces-1_1_1, which was fixed by Andy Clark after I reported it.

1) Simplified database connection creation by adding new utility routine in MetaCatUtil that reads configuration information from the properties file.
2) Created MetaCatUtil.getOption() to retrieve options from properties file.
3) Unified SAX Parser creation by specifying parser driver in the properties file and dynamically loading it using the XMLReaderFactory interface....

cleaned up code for getting options from the properties file, made the database connection inthe MetaCatUtil class use the properties file for the conneciton info

updated javadoc documentation

updated javadoc documentation

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

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

no message

new class for registering of Accession numbers into metacat db

renamed DBSAXWriter to DBWriter

updated classpath to use jar file in shell scripts

reincorporated Title registration code for documents

updated stylesheet script to reflect new table structure

updated documentation

updated jar file

Renamed DBSAXElement to DBSAXNode

rearranged API for incrementing the node index within the parent node
