[ZOO-PSC] FOSS4G Call for Workshop

[Venkatesh Raghavan]

Hi Gerald,

When papers presenters can submit multiple abstracts, I do not
see any issue in submitting two proposals for workshop.
Bacsically, I suggest submitting one proposal for users
who wish to deploy existing pre-existing ZOO-services
and another for developers who wish to develop new
WPS on ZOO. Gerald's proposal as WS for developing client
and WPS on server side is a good idea, I think.

Tutorial topic could be more general perhaps something
in the line off "Introduction to the ZOO-Platform - A
Integrating FOSS4G tools to deploy OGC Data and
Geoprocessing Services"

It would contains an overview of what is doable using WPS specification (including parameters description and use cases) and its ZOO-Project implementation. We will mainly present here advantages of using the WPS standardized communication protocol when developing Client interfaces and what WPS is able to provide to a client in term of functionalities (storing result on the server side, execute request to run the processing as a background task, introducing chaining through the simple use of result of a process as input for another one and so on). We can also plan to make some demonstrations using the QGIS WPS Client to communicate with ZOO-Kernel as it is already working (you can see it here [1]). A small OpenLayers client can be used to display map, access their properties through WFS/WCS, then process the data using WPS passing WFS/WCS features as parameter and di

This should not contain the section about OpenLayers. Indeed, I think that here the most important point is to present how it is simple to implement new services not how to integrate them with a client side application, the client side application can be view in introduction and ready to handle all the services which will be developed during the workshop by attendees. This mean, process but also display result and things like that. We can start using the OpenLayers client using at the beginning the existing C implementation of the services which will be implemented in Python during the workshop.

The capabilities of ZOO-API will be pointed out and how you can manipulate the data coming from one service, pass them to another service and then combine both.

I know that it is a huge work to prepare a workshop, but from my point of view, last ZOO-Project FOSS4G Workshop was also a big advantage for our project as we provided good material introducing services implementation using ZOO-Project, I think.

This can also mean even more work to provide tutorial version (lightweight) and workshop version but then better material for ZOO-Project users in the future which is also important. We also have to think on what is the best way to gain workshop attendees interest, that is why I think at least two workshops have to proposed, one for the users and one for the developers.
