[ESIP-AQ] Fw: NASA comments on IOC

Fri Dec 12 13:05:02 EST 2008

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...

NASA comments on IOC

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:
