Hi everyone,

Bruce, to my recollection, the September '07 Geonetwork technical 
meeting did not say a production version would be ready in a few weeks, 
instead I recall that BlueNet was asked to develop a basic version 1.0 
metadata entry tool which included the ANZLIC profile - that was 
delivered. Everything since then has been version 1.1 :-). Note: the 
MEST is based on Geonetwork 2.2 and has been since BETA4 in early March 
- so it's not behind anyone :-).

Up until last month we've fed a lot of the code from the MEST back into 
the trunk but there is a need to write proposals and get them approved 
by the community before some of the later changes can be committed. 
Community approval is a good thing but it takes time to get this 
together and slot things in to the trunk - that time lag would be a 
problem for anyone (not just BlueNet) - especially when the priority for 
us has been features we need.

BlueNet did also commit to coordinating development of the MEST release 
with the trunk (at the Sept '07 meeting) - which we've done - indeed 
there hasn't been much of the usual danger of 'fork'ing :-) because 
we've been pretty assiduous at keeping the MEST synced with the trunk.

In the absence of a plugin architecture for profile support, then maybe 
the following would be steps forward:

1. Get rid of the word BETA (and MEST which I don't like either) - the 
current code is based on 2.2 final anyway - the BETA label is just 
something BlueNet has used because it has shown our progress toward 
having a production tool that we can use for the BlueNet researcher 
workshops to be held over the next few weeks. The next release will be 
the final because we've frozen for the workshops now. Maybe calling it 
GeoNetwork 2.2 ANZLIC would be less confusing (the current BETA5 already 
has an 'About' menu that tells you a bit about who did what and when).

2. We need to develop and submit proposals for the functions that were 
added recently to GeoNetwork 2.2 ANZLIC (or whatever we finally decide 
to call it) and that are not in the trunk - we need to keep the number 
of differences between GeoNetwork 2.2 ANZLIC and the trunk to a minimum 
because it makes syncing with the trunk easier. BTW: It's not only skins 
Byron - its also about slightly more fundamental things not yet in the 
2.2 trunk eg. saxon for xslt2, temporal search, separating editing & 
ownership rights, remote html in Z etc

3. A set of instructions needs to be provided that will allow anyone to 
take the profiles from GeoNetwork 2.2 ANZLIC and add them to an install 
of the raw trunk. This would suit those that want to customise the trunk 
for themselves. (I think this is what Byron was suggesting?).

This all needs more discussion - but in a positive way - its not about 
lack of progress - its more about the expanding community, changing/more 
sophisticated needs and moving on from the things we agreed at the Sept 
07 meeting.

Cheers,
Simon

Then, as now, I determined GeoNetwork to be the "best of breed" software for performing this duty.  The fact that it was Opensource was, in my mind, a plus.  Since that time I have moved into the role of GIS Developer, but the implementation and support of GeoNetwork has remained a major focus of my work.  Today we have approximately 1500 records in our catalogue and are running GeoNetwork 2.1 and will soon be migrating to GeoNetwork 2.2.

The fact that they latter did so made it much easier to convince managers that this was the right path to take - particularly after the decision by BlueNet to include the ANZLIC and ADO profiles was made.

> To date, I have not implemented any of the BlueNet versions of GeoNetwork.  At this point, I am unlikely to do so in the near future.  There are many reasons for this, and I would like to elaborate on a few of them.  First is the problem that you identified, Bruce - the tool has not moved out of Beta and watching the trac, I am uncertain when this may happen.  Another reason is that we have been ahead of MEST in release versions.  I had already moved to GeoNetwork 2.1 when the MEST was at 2.0.3. 
>
> Most importantly, the MEST tool is becoming more than what we want.  What I mean is that we want a tool that includes the ANZLIC and ADO profiles and MEST does that, but I am not so interested in the gui changes on top of GeoNetwork.  Not that many of them aren't useful improvements, they are, and I would use them if they were included in core GeoNetwork.  Luckily, Simon is a core contributor to GeoNetwork so it is likely that much of his work will merge back with trunk.  But I have done my own customising of GeoNetwork to meet our own needs and for sake of simplicity, would rather apply these changes to trunk GeoNetwork trunk rather than a fork when GeoNetwork updates come.
>
> I am very interested in improvements to GeoNetwork that would allow the ANZLIC and ADO profiles to be more easily plugged into my own implementation of GeoNetwork.  GeoNetwork contributors like Simon Pigot and François Prunayre have been looking at this.  I am willing to contribute whatever help I can if this is important enough to get GeoNetwork more broadly implemented in the region, but right now my GeoNetwork development efforts are more in the areas of automated metadata capture and workflow aids.
>
> To sum it up, I am interested in the tools of MEST but not so much the skin. I for one, would like to see the name MEST disappear.  It adds confusion in that I find myself needing to explain that "MEST IS GeoNetwork" again and again.  At least the release numbers could be synced.  And, as I have indicated, it would be useful if the tools improvements in MEST, especially the profile schemas, could be separated from the gui improvements.

> Some of these problems I believe are inherent in government trying to adapt to the world of Opensource.  I think that we as a group can and should help.  Asking a contractor to perform work that is open source is new to most administrators and developers in government.  At least I am finding this to be true as we have hired contract support for developing an automated metadata harvester that I am developing to run along side GeoNetwork.
>
> Another problem I see is one that seems inherent to Opensource.  This problem is forking of the source code.  I am worried that MEST may become a permanent fork of GeoNetwork and I do not think this a good thing.  Luckily, since Simon is a contributor to GeoNetwork, this risk is somewhat minimised, but by no means removed.  As we pool our efforts to develop MEST we need to keep very clear on what is MEST specific and what is general GeoNetwork in order to avoid the forking problem.
>
> A third problem I see is one that seems inherent in metadata itself.  What I have seen through my career is what I consider an over-emphasis on getting the model right before implementing anything.  While the proper schema is important, I did not think that the lack of a ANZLIC or military profile was sufficient reason to delay our implementing a metadata solution now.  Yes, it does mean that we will need to revisit all we have in our system now will need to be revisited when we implement a different schema, we would need to do this anyway when the schema changes - and the schemas will change, or our own definitions of how the schemas be completed change.  What is important is that it helps us do our work. GeoNetwork is good now.  I see no reason to delay implementing it.  What we need is a good community of local developers and users to help others with implementations and migrations.
>
> I think GeoNetwork is an excellent opportunity to prove once again the worth of Opensource - particularly for GIS.  There is very little out there to compete with GeoNetwork capabilities in the metadata catalogue world.  And as we all know, the payoffs to a well functioning distributed Metadata Catalogue network would be enormous.  More than anything, of course, open source is about the community.  Combining our efforts to finding solutions to the MEST-GeoNetwork problems is just what open source is about.  I feel that part of the failure of MEST to progress faster is that it has fallen into the old model of just hire someone to do it and wait for the results rather than do it ourselves as hackers are wont to do by nature.
