Subject [greenstone-users] Seeking plug-ins for program objects
Before writing any plug-ins to help ingest computer programs into a Greenstone library, I would like some information. 

The background is a Computer History Museum (CHM: see http://www.computerhistory.org/) collection of 75,000 files recording the development of the Snobol and ICON programming languages.  This collection is being used in a pilot service to test and demonstrate the suitability of GSDL as a component of CHM infrastructure.  Most of these files belong to datatypes not represented among the plug-ins delivered as part of the GSDL 2.72 distribution; many of these are computer programs with modest internal comments that could be used to construct search indices.

(1) Has anyone written plug-ins for computer program and related document types?

(2) More generally, is there anywhere a listing of available plug-ins beyond those distributed with GSDL 2.72?

(3) Having ingested the Snobol collection into a "vanilla" GSDL 2.72 instance, the normal collection interface on the Web shows only about 6000 of the 75,000 collection members.  Am I correct in supposing that the shortfall occurs because the other 69,000 files are not represented by plug-ins?

(4) Does some reader of this posting know a convenient way of showing the tree structure of the nested 3000 directory organization of the input collection?  Or of showing a browsable list of all files and directories in the same original directory as some file that has been selected by using existing GSDL search services?

Cheerio, Henry
