2.0 - underway

New features:

abstract hosting - refining...: Abstract functionality of bookmarks and annotations scripts. Potentially merge the two into a generic RDF metadata service with handlers for specific forms of POSTed data.
database optimization - refining...: Provide support for hetrogeneous database with optimized annotations/bookmarks-schema specific relations.
schema annotation parser - refining...: RelaxNG annotated schema drives the RDF parser.
Remove deprecated support for form-urlencoded POSTs without a parameter name.

CVS version identifier: -none- (or HEAD)
This version should be checked out without a version number.

1.2 - 14 April 2003

New features:

bookmark server - refining...: Added support for bookmarks with a W3C/Annotations/CGI/bookmarks script.
XML namespace rigor: Ensured that POSTed data had valid XML namespaces including in the rdf:parseType="Literal" elements. This impacts annotea clients POSTing XMLLiteral data without namespaces, for instance, old Amaya clients.

Bugs addressed:

W3CDebugCGI's `date` call not portable - done (CVS): Incorporated Matthew Wilson's patches.
XSD datatype support: Strings are now indexed by their MD5sum and their encoding and their XML datatype. This change requires an upgrade script.

Upgrade actions:

install perl Time::HiRes module

W3CDebugCGI now uses Time::HiRes which is available in the debian libtime-hires-perl package:

apt-get install libtime-hires-perl

execute W3C/Rdf/bin/AddDatatype.mysql

The new database has a change to the schema. The Strings table now has an additional datatype field which is part of the unique index u_md5hex_datatype_encoding. The AddDatatype.mysql MySQL script adds a datatype field to the Strings table and re-indexes:

cd W3C/Rdf/bin
mysql < AddDatatype.mysql

CVS version identifier: V1_2

1.1 - 2 April 2002

Bugs addressed:

String Collision: Strings are now indexed by their MD5sum and their encoding. This change requires an upgrade script.
form-urlencoded POSTs without a parameter name: The code that tolerated this was removed from W3CDebugCGI. Temporary workarounds were placed in annotate. These will likely be removed in 2.0.

Upgrade actions:

execute Strings-substringToMd5hex

The new database has a change to the schema. The old Strings.substring has been removed and replaced (in functionality) by Strings.md5sum. The Strings-substringToMd5hex script updates this table and checks for collisions in the use of Strings records:

cd W3C/Rdf/bin
./Strings-substringToMd5hex

CVS version identifier: V1_1

1.0 - ? 2001

New features:

annotation server: There was no annotation server versioning before this. There was afterwords. I think that's a feature.

CVS version identifier: V1_0

Bugs

W3CDebugCGI's `date` call not portable - fixed

W3CDebugCGI logs all sessions with a session id composed from the time. This call to time is not portable to windows.

form-urlencoded POSTs without a parameter name - fixed

W3CDebugCGI's logic used heuristics to decide what content type something was and whether to url-decode it.

String Collision - fixed

Strings with a common initial substring longer than 255 chars were assumed to be the same string.
