Forwarding a copy to the mailing list:

Hello Doug,

The ticket number 426 at Trac has not been updated to reflect the
Greenstone Team's more recent discussions on the topic. It seems likely
that we will be trying to use Open Office as an alternative means of
converting various documents--particularly the different kinds of MS
Office documents, such as .docx, ppt--where this is installed, else we
may default to using the current conversion tools.

You are right that a plugin to handle Open Office documents is also a
requirement. Our present thinking at this stage is not to parse the docx
or other MS Office formats ourselves, but to rather use Open Office's
ability to convert them. Similarly, we might try to use Open Office
itself to convert Open Office documents or otherwise fall back on the
OpenDocument plugin (see below).

Your intention in writing a plugin for OOXML sounds like it might not
require Open Office to be installed in order to accomplish the
conversion to HTML, is that right? It does sound very helpful.

> I haven't dug into the OpenDocument plugin,
At present, the OpenDocumentPlugin.pm seems to extract only the text
from the document, going by what the starting comments say:

# Processes OASIS Open Document format.
# Word processing document: .odt, template: .ott
# Spreadsheet document: .ods, template: .ots
# Presentation document: .odp, template: .otp
# Graphics document: .odg, template: .otg
# Formulas document: .odf, template: .otf (not supported)

#This basically extracts any text out of the document, but not much else.

# this inherits ReadXMLFile, and therefore offers -xslt option, but does
# nothing with it.

Regards,
Anupama
