[Geodata] meeting narrative

Dear all,

We're working on packaging data and metadata that than can be  
directly imported in e.g. a GeoNetwork catalog. We've defined a  
packaging format, very light weight, that contains some meta-meta  
information, the actual metadata, preview images, basic privileges  
and possibly also the data itself. We named it the MEF format  
(Metadata Exchange Format), but it really just is a zip file.

In GeoNetwork we have added import/export routines for this format.

We're developing a plug in for ESRI ArcCatalog that generates the  
format and we also discussed with the gvSIG developers who will most  
likely also add support for it.

We're also discussing with the gvSIG folks to develop a bot that will  
search a directory, generate metadata and create MEF files that can  
than be harvested by GN.

The format is not the solution to everything, but for our cases it  
works. It's been described in our documentation and we're open to  
further improve/extent it.

Maybe something to consider for the data dump bucket!?

Here's a link to the document describing MEF in chapter 3:

Ciao,
Jeroen
