Hi all,

Sorry for cross-posting.

held at TNC.

BOF: Collaborating on Collaboration: are we going somewhere?
3 June 2010
Vilnius, Lithuania
Notes: Licia Florio


1.	Introduction
This BoF explored opportunities for NRENs to collaborate, discussed some
of areas in which collaboration would be desireble and identified
use-cases that would benefit from such collaboration. The BoF also
looked at TERENA’s role to support NRENs collaboration.
The attendees split in sub-groups each of which provided their use-cases
for collaboration. The following use-cases were identified.

2.	Use-cases emerged during the BoF
Group 1
This group looked at models in which services could be offered, namely:
-	One NREN providing a service for everybody. This model can work for
wikis, conference-call facilities or more in general for services that
are already available on the market for which customization is needed
rather than development. Other NRENs would ‘buy’ the service they need
from the NREN that offers them.
-	NRENs collaboration to finance outsourcing development; an example of
this is the TCS eScience portal.
-	NRENs could collaborate also on policy issues. It was noted that
similar issues are addressed by TF-MSP, the TERENA Task-Force on
Management of Service Portfolios.

In what concerns TERENA’s role, this group indicated the following:
- Offering a meta-service (similar to service-catalogue) to collect and
list all services NRENs offer. Andras Kovacs noted that a similar thing
was created a few years ago to support H.323 services, so he wondered
whether this tool should be revitalized and expanded. Ken Klingenstein
noted that ideally such a catalogue could encompass also services
offered beyond Europe (a sort of a trans-Europe service discovery
capability).
- Offering an adobe service to all TERENA’s members.
- Offering a jabber server for all TERENA’s members.
- Offering a code repository.
- Offering a COmanage service.


Group 2
The use-case identified by this group concerned lobbying. Some of the
attendees feel that the R&E community is not particularly good at
promoting themselves as whole.
Areas to lobby would include Data Protection and service providers.
Licia Florio noted lobbying is also in the REFEDs scope.

It was also noted that identifying who (which NRENs and which person
within the NRENs) is doing what is not always trivial; one possible
solution to address this issue would be to offer a federated XMPP that
would glue various information together. TERENA was nominated to run
this service.

Group 3
This group identified the following use-cases:
-	Services across NRENs boundary, for instance the TCS portal could be
re-used (or modified) to offer a European MCU reservation system. In
this case it would be interesting investigating the costs as well as the
user’s support for such a system.
-	Support for VOs at international level - Niels noted that NRENs should
really offer this as NRENs are already supporting collaboration at
various levels. A light-weighted approach to address this need would be
for NRENs to offer and package the VO software and let the VOs to
operate that. This point also raises the issues on how to federate VOs
platform, i.e. LIGO (www.ligo.caltech.edu/) is already used in many
countries.
Niels suggest creating a small group to discuss VOs collaboration tools,
which would hold monthly conference calls. He volunteered to lead the
group.
It was noted that duplication of work should be avoided. Work on VOs
platforms is planned in GN3 and support for VOs is also one of the
topics on the REFEDs roadmap. Licia Florio suggested scoping the
use-cases and verifying whether some of them could be addressed by GN3
and TF-EMC2.

Group 4
This group identified the possibility of sharing security tools as a
use-case for NRENs collaboration. The group also indicated the
domestication of application as a use-case. Domestication has to be read
as using applications that can handle out-of-band identity provision and
vetting and can support roles defined outside the application.

3.	Summary
All the attendees agreed that the NRENs community mostly shares
documents and best practices and they could further share calendars
(especially in the case of people working on a common project).

Alex Reid noted that most of the content sharing takes place at campus
level (shared classes, courses and so on), so he suggest understanding
what NRENs should do to support collaborative tools and to identify the
boundary between the NRENs relevance and the NRENs relevance.

On a more general note attendees noted that collaboration would help
NRENs to offer some services which NRENs would not be able to offer
alone; TCS was mentioned as an example of this.

One of the issues identified by the attendees is how to discover what
NRENs are working on. It was noted that the TERENA compendium contains
some of the information, but it was suggested setting up a registry to
address this point (or a service-catalogue); pros-cons of  such a tool
should be evaluated.

The need to have applications that can handle out-of-band identities and
can support roles defined outside the application was also discussed;
this falls into the domestication area. It was noted that NRENs are not
best positioned to turn into application developers, but they should
talk to specific service providers and software vendors and present to
the NRENs needs to them. Lobbying in this area would help.

Tools to support VOs is a hot-topic; it was agreed to define use-cases
and to start discussing them on the EMC2 list, which reaches out beyond
Europe.

It was also agreed to engage more with TF-MSP to discuss tendering
procedures and cost-sharing models. For instance if the NRENs would
agree to do more on the federated XMPP, would this be a topic to be
discussed within TF-MSP?

As far as TERENA is concerned, attendees identified a number of services
that TERENA is well positioned to offer, such a COmanage service, adobe
service, jabber server.
Niels and Licia agreed to look at some of the proposal and investigate
their feasibility.
