Thanks to Eliot Christian for catching a key 
omission in my notes!

 

Meeting notes for October 7, 2003 OASIS EM GIS SC 
Teleconference

 

In attendance: Carl, Elliot, Rex, Thomas, Clark 
(for ESRI), Gary, Gopal

 

1. Had a short discussion on Forms. Agreement that 
while there is no way the GIS SC can 
influence commonalities content and structure standards 
for Government Forms across all Government.  We 
can make progress on the smaller subset of EM-relevant forms so long as we 
accept that some obviously common elements (name, address...) may be differently 
defined across communities of practice. (Eventually a common 
semantic registry is envisioned to help with this broader issue, but that has 
been very slow in getting off the ground.)
We also 
discussed documenting best practices for coding geospatial elements 
that are in these forms. Examples of best practices might be how to express a 
coordinate reference systems (e.g. WGS 84) and recommendations for geocodes, 
such as the ISO standard for country codes (editor's example).

 

2. Short discussion on the Symbology 
Interoperability Requirements document. No changes other than recommended 
edits/additions received via email. Carl is to collate, update and repost by 
Friday, Oct 10. Should be viewed as a fairly stable position and recommendation 
document.

 

3. Good discussion on what the GIS SC should do 
next. Discussion focused on best practices and approaches for using XML Schema 
for encoding EM Symbology content (art work). Following was 
suggested:

  
Let's take a look at what other work has been done 
  in this area and evaluate and then determine if it is useful. 
  
Need to develop a controlled namespace 
  (vocabulary) for symbology names that could be used for a EM symbology 
  registry and Web Services interfaces. Subcommittee could define or recommend 
  an interface for accessing and portraying EM symbology. DMIS said that if such 
  an interface existed, they would be willing to test it. 
  
Discussion on symbology, layering, operational 
  pictures. Questions concerning separation of EM symbology into separate 
  layer(s) as well as (or as opposed to) EM symbology being displayed as part of 
  an existing GIS layer being served up from some GIS database. 

These discussions will continue during our next 
teleconferences.
