Notes

(Thanks to Phil Warner, NOAO, for being note-taker!)

Capture about compilers.

How much build information should we provide.

What, at registry level do people need to know about search capabilities, etc.? What information to have displayed.

Compiler may not be useful. C#, .NET, astronomer wants to get information in as few clicks as possible.

Multiple uses of registry Users Developers

Too much - people won't read Too little - not enough

Separate into categories?

Specify dependencies (libraries, compilers, version numbers)

Added "Dependencies" section. are deps registered? deps may be IDL (link)

NetworkRequired y/n is not enough? Essential/Useful/Limited/Unnecessary

some criteria to whittle down - keywords by which to whittle down the list (e.g., for sorting) - sort of sourceforge {note-taker's addition: freshmeat or packages.gentoo.org} - what can I use in my development of _? or - what can I use in my research?

Bob went onto google to find places that categorize metadata name/text, no more why has no one else done this?

useful for workflows? what workflow engine needs to invoke if populated well, will allow to build workflows and find code

ongoing cost involved (human)

cost? description of pricing, if not freely available. optional?

Addition to "license" : ...including cost information

focus on Functionality - interactive/command-line/script/etc.

added VOStandards section - supported standards and protocols used or implemented

added ControlModes section - Interactive, command-line, scriptable, from browser, etc.

NVO project has had a registry of tools/software - nvo website->tools (list of 15 applications + five others)

machine consumption metadata services registered by service type this if focused on end-user applications

these metadata are placed into detailed schema

=============================

do we incorporate into resource metadata document?

get 1.1 out the door? make this the next iteration?

What else in 1.2? this is it.

push through 1.1 first, let this follow with 1.2

==============================
