3. www.vektrex.com - slide 3 3 x Confidential Importance of ATML Tools Tools involved in almost all ATML usage cases –Broad ATML tool adoption = ATML Success Tool development an essential part of schema validation –Many XML platforms don’t support all Schema constructs –Key relationships may be missing Iterative “Tool Development”/”Schema Changes” key to getting optimal ATML Schemas

4. www.vektrex.com - slide 4 4 x Confidential ATML Tool/Schema Challenges Platform Support Issues –Object Oriented Data hosted in relational DBs –Schema constructs not supported Application Issues –Inter-document relationships Example: Test Configuration, Instrument Description, UUT –Intra-element relationships Example: Instrument Description (Ports & NetworkList)

5. www.vektrex.com - slide 5 5 x Confidential.NET Platform Experience ATML Instrument Description Editor ADO.NET (.NET XML-DB binding technology) doesn’t support current ATML schema XML Spy generated code – problems with abstract elements.NET Serialization worked Application Issues: –No common way to link documents (e.g. Components) –Relationship between linked elements not clear (e.g. Ports & NetworkList)
