[ome-users] Have you written some OME STs, would you like to keep using them?

[Tom Macura]

Hello,

If you've written Semantic Type Definitions and are using them with  
your OME installation you need to be aware that we are planning (post  
the 2.6.0 release) to make major changes to the underlying OME Data  
Model.

PLEASE get in touch if you have any  questions or if you think these  
changes might affect you.

Firstly, we will enforce the new requirement of "one ST per table,  
one table per ST". In the past (i.e. now), a semantic type's semantic  
elements could be distributed in multiple database tables (e.g. like  
in the example below, tables ST_TEST_A and ST_TEST_B). Secondly the  
DBLocation will be optional (if you don't specify it, OME will give a  
default  DBLocation).

So if you used to have an ST like so:
		<SemanticType Name="FirstST" AppliesTo="G">
			<Element
				Name="ABC"
				DBLocation="ST_TEST_A.ABC"
				DataType="string"/>
			<Element
				Name="DEF"
				DBLocation="ST_TEST_B.DEF"
				DataType="integer"/>
		</SemanticType>

Now you'd use:
		<SemanticType Name="FirstST" AppliesTo="G">
			<Element
				Name="ABC"
				DataType="string"/>
			<Element
				Name="DEF"
				DataType="integer"/>
		</SemanticType>

Do you have STs that break the new rule? We'll help you with the  
migration, but please let us know.

Sorry for all the pain involved on all sides but ultimately this  
change will expand OME's data-modeling capabilities by allowing  
multiple outputs of a particular Semantic Type in Modules.

Best,

Tom
