IWF Metadata Harvester

Posted to Code4lib.

I'd like to announce the publication of the IWF Metadata Harvester.

This package reads data from servers, writes it to databases, implements various kinds of searches, and writes HTML files to display the results. It currently handles data from two kinds of interface: OAI (Open Archives Initiative), which provides XML, and Z39.50, using the Pica format.

The IWF Metadata Harvester is Free Software. The program code is published under the terms of the GNU General Public License, and the documentation under those of the GNU Free Documentation License. It is available from this FTP server. I am currently looking into the possibility of having the package hosted on a website for software developers.

The IWF Metadata Harvester has been developed on a system running Microsoft Windows Server 2003 and using Visual Studio, Visual C++ .NET and Microsoft SQL Server 2000. However, I have tried to make it as portable as possible under the circumstances by avoiding the ATL and MFC types, classes, etc., as much as I could. However, it has not been possible to do without them completely. More recent code uses them less. I hope that it will be possible to use the files of SQL code with free database packages without too many alterations. I plan to port the package to GNU/Linux myself at the earliest opportunity.

I have used Donald Knuth and Silvio Levy's CWEB package for the C++ code, so that pretty-printed versions of the programs are included in the package. This directory also contains the manual, which has been written using the Texinfo package. It is available in the following formats:
DVI, PostScript, PDF, and HTML.

Because the IWF Metadata Harvester is Free Software, libraries, archives, or any other providers of metadata could make it available to users with no purchase, registration, special license arrangements, or (subject to local laws) liability.

The IWF Metadata Harvester is a work-in-progress. I would be very interested to know whether any libraries, archives, other institutions, businesses, or private persons would find it useful.

Any feedback would be much appreciated.
