[ESIP-AQ] Fw: NASA comments on IOC

Fri Dec 12 13:23:14 EST 2008

Hi all,  thanks David for sending this around.  I'm stuck at home and may not be able to sit in, though I will try and deal with the 3 year old.  If I miss I'd really like to hear/see your feedback, ideas, etc.  This very much ties in to some upcoming meetings Stefan and I are working an agenda for.

thanks, back to daddy-care.

cheers,

f

Hi all, 

Afraid I will miss today's telecon. 

Two interesting things that I wanted to send along.  First, below, from Frank Lindsay is a document he sent to USGEO-ADM offering a) NASA concerns about the GEOSS IOC (initial operating capability and b) a list of components and services they intend to register. 

Hopefully, those of us at EPA will produce something similar in January.  I hope we will be able to get feedback from ESIP folks as we do that.   

The second will come in a second email in a minute...

Hello to all,  sorry for this late entry into our discussion for today on the GEOSS registries.  We have had some fruitful discussions here and wanted to share some of our thoughts, in brief, on the work ahead.  Hope this is helpful!  I attached a word version as well.

best,

Frank

-----------------

The GEOSS Common Architecture (GCI) and IOC have revealed critical implementation lessons for developing a distributed, global system of environmental information providers and consumers.  The next phase in the development of the GEOSS IOC is to plan for and execute the operational build to architecture.  Commensurate with this next phase, it is necessary to establish the operational architecture of computing and network components and a governance structure for the system including the systems plan for ongoing maintenance.

Implementation issues have arisen during the initial phase of the IOC that, while challenging, have been useful in understanding how US agencies will input information into the system.  NASA sees challenges involving several key areas of the system, including:
.  the granularity and exposure of services
.  the underlying taxonomy for the organization of components and services
.  weaknesses and trades in the interfaces to the GEOSS Clearinghouse
.  'gate keeping' (or oversight)  needed to ensure that registered components and services are sanctioned by authorized agency representatives so to avoid incomplete or erroneous information being presented, and
.  the integration of community portals and the manner in which registry components and services are represented in these portals.

The IOC activity has helped to reveal the opportunities and challenges that US agencies contributing to the GEOSS will face.  The next phase involving "Build 2.0" of the system can capitalize on these experiences producing a robust system that will enable the discovery and access of data and information across multiple countries and organizations thus meeting the 10 year implementation goals for GEO.

As one example of current participation NASA has several key components and numerous services registered in the GCI registries.  These entries have helped NASA understand how aspects of the IOC create challenges in our full participation.  The following list is representative of some of these entries:
