[cosmos-dev] RE: Schema for simple sdd registry

[Jason Losh <Jason.Losh@xxxxxxx>]

Hi Josh,

I saw your other email that you have much of this working already.  Nice work.  We can discuss those remaining questions on the architecture call tomorrow.  I made some tweaks to the schema that you sent out though.  I plan to look at it further tonight and may make a few other modifications.

The major changes are that I removed the order attribute.  In addition, I added an id attribute which is a placeholder for mapping back to the SDD id.  I considered making this a UUID, but did not since the IDs in the SDD must be unique and are already based on a UUID construct.  I also added a VersionType complex type to house a VRML based version scheme of major.minor.patch.fix.  However, I made major the only required attribute and all are strings so if adopters don't use the VRML convention any valid xsd:string can be used within the "major" attribute.  I also made version a required element of ProductType as it didn't make sense to me to install software without a version identifier.

There were a couple of other minor tweaks I made that you'll see.

Please review and let's discuss this and your remaining questions tomorrow.

Cheers,
-Jason

Not sure why this didn't go out the first time, trying again.

All,

Here is the schema for the simple xml based registry for storing information about resulting resources.  Please review it and let me know what you think.

Thanks,
