Thanks for the tip; the .xml files have the info I need.

Since I have a few dozen directories (in my test case) and this is on a Windows machine, I am at a bit of a loss as to how to find the hash code for a given document ... I could accumulate all of the relevant lines from the .xml files (<Metadata name="Identifier">HASH010ddaf18d9e03d233379b41</Metadata>, etc.) and put them into a dbm or other easily searched format. Or code a tool that searches .xml files in directories (and sub-directories, and perhaps sub-sub-directories ?) for the proper .xml file and then extract the hash.

I was wondering, I suppose, if there is a function call that, given a file name would calculate the hash. I've been poking through various perl modules without luck so far ... (slightly slow going, lots of neat aspects to the code).

Thanks for the help,

Greg Williamson

hi greg,

I am assuming that you want to click on a point in the map and go directly to a document. if not, please ignore the following stuff.

to display documents, the greenstone cgi arguments are like

where c specifies the collection name, and d specifies the document identifier.

if you know the identifiers of the documents (and these are specified in the archives doc.xml files), you can easily link to them from your map.

hope this helps,
Katherine Don

I'd like to be able to have my map user click on a point and end up seeing the page displayed by Greenstone. Ideally our data points will store the file name of interest and the Mapserver application will format that file name into a string for Greenstone or some intermediate program.
