[Oai-pear-devel] PEAR::OAI 0.3 released

[Sandro Z. <san...@zz...>]

  The PEAR::OAI developers team is happy to announce the immediate 
availability of PEAR::OAI 0.3.

### Description ###

PEAR::OAI is a PHP class library for the Open Archives Initiative 
Protocol for Metadata Harvesting (http://www.openarchives.org). This 
library provides a Server (= Repository) and in the future also a Client 
(= Harvester) interface. This package is conformant to and makes use of 
PEAR (http://pear.php.net) classes.

### Featurs ###

- full OAI-PMH version 2.0 compliance (tested with OAI Repository 
Explorer, http://oai.dlib.vt.edu/cgi-bin/Explorer/oai2.0/testoai)
- easy and flexible configuration (well documented)
- object oriented PHP
- compressed XML support, which greatly reduces used bandwidth
- can connect to many existing databases, by using PEAR database 
abstraction layer
- modular container-class-system allows plug-in of several data storage 
interfaces that wrap different data structures
- integrated IT-template system to provide arbitrary metadata format output
- PEARDoc (~JavaDoc) inline documentation
- garbage collection of resumption tokens (via PHP session functions)
- resumption token sessions can be stored in filesystem or database
- checking expiration date of resumption tokens
- debug mode to track errors in logfile

### Changelog ###

New Featurs:

- almost full OAI-PMH version 2.0 compliance (tested with OAI Repository 
Explorer, http://oai.dlib.vt.edu/cgi-bin/Explorer/oai2.0/testoai)

- requires PHP greater or equal 4.2.0 due to session bug in PHP 4.1.2

- debug mode to track errors

- checks if resumption token is within expiration date

- added OAI_Base::getPackageVersion()

- automatically compose sample identifier

- store tokens either in filesystem or DB (using PEAR::HTTP_Session)

Bugs fixed:

- empty response with gzip encoding

- OAI Repository Explorer error: "White space is required between the 
public identifier and the system identifier" caused by wrong assignment 
of OAI schema location constant

- OAI Repository Explorer error: "Datatype error: In element 
'repositoryIdentifier' : Value 'aName' does not match regular expression 
facet [a-zA-Z][a-zA-Z0-9\-]*(\.[a-zA-Z][a-zA-Z0-9\-]+)+'.."
-> changed aName to example.com because dot is required

- OAI Repository Explorer error: "The content of element type "metadata" 
is incomplete, it must match 
"(##other:uri=http://www.openarchives.org/OAI/2.0/)" 
<http://www.openarchives.org/OAI/2.0/%29%22>;.
-> caused by left-over opening and closing metadata tag when showing 
deleted records

- datestamp in GetRecord and ListRecords was not UTC conform
