DMAC ST and the Activities of the IOOS PO Derrick Snowden DMAC Steering Team

The recent IOOS summit issued a few recommendations or challenges wrt DMAC Clear instructions on how to participate Define a way to measure progress Presentation Objective Recent progress and near term plans for IOOS in the context of these two challenges

Great, a challenge, now what? Clear instructions to participate – (in what?) Metrics for progress – (towards what?) depressive-illness-confusion-and-fear-of-sanity/

The “what” of DMAC means different things to different people, particularly the system aspects.

There are several valid descriptions of “what” DMAC is GEOSS Architecture AIP-6Architecture EarthCube Concept Groups esp. Layered Architecture Cross Domain Interoperability NOAA Environmental Data Management Framework (v0.4) Alternatively, these are efforts to define the scope of the system we need.

The trouble with catalogs… 8 Illustrates the Publish, Find, Bind Pattern. OGC Reference Model (OGC r7) IOOS GEOSS WMO WIS data.gov One of the summit requests was for metrics to measure progress and community catalogs offer one possibility to focus on. More and better data services, more and better tools to use data, all data and tools registered in a catalog somewhere.
