wvware can do this (I've no idea if the plugin can). There's a
utility in the wvware package called wvSummary. From the man page:
wvSummary - view word document's summary info
wvSummary displays the summary info included in all MSWord
documents. This often includes the Author, time created,
Here's a sample output:
[ild64;bychan pc]$ wvSummary Test.doc
The title is Test Document
The subject is Just to test the document property extraction
The author is Illtud Daniel
The keywords are wvware greenstone word bill gates satan
The comments are This is the comment field, which can
contain lots of words.
The template was Normal.dot
The last author was Illtud Daniel
The rev # was 2
The app name was Microsoft Word 8.0
PageCount is 1
WordCount is 38
CharCount is 130
Security is 0
Codepage is 0x4e4 (1252)
It hasn't picked up the custom properties fields which I added
but I don't see that it would be much work, if wvSummary can do
the standard fields.
It should be possible to write a plugin that uses wvSummary to
extract the properties into metadata for Greenstone.
The above is all based on wvWare 0.6.5, and the current release
is 0.7.2, but the summary stuff doesn't seem to have changed. There
*is* some sort of xml format for specifying the output, and
the docs suggest that you could write an xml file which would
dump the info straight into an xml format of choice (gml?),
but I can't find documentation on how to produce the xml file -
there are many examples, though.
The custom properties can be read from the OLE stream - see
this translated Italian page from MS:
The references section contains:
The information on Ole Structured Storage are in text MS Press: "Inside
OLE - Second Edition ", Brockschmidt, Understood It 7: Structured
The information on the modalita` of access to the ' Summary Information
Set' of a Ole Document Compound is on MSDM in: Platform SDKCOM and
ActiveX object servicesCOMStructured StorageUsing Property Set.
I might have a look at the book mentioned - the libole2 stuff in
wvWare is simple enough even for me to understand. It'll be on
the shelves here somewhere!
