1. GJXDM Tool Overview Schema Subset Generation Tool Demo

2. Information Technology and Telecommunications Laboratory May 2005 Problems Large Schema  Slow validation  Difficult to search  Tool problems  Hard to trace through

3. Information Technology and Telecommunications Laboratory May 2005 Limited Area of Interest The full data model what I care about

4. Information Technology and Telecommunications Laboratory May 2005 A Solution Schema Subsets: 1. Determine requirements: What part of the data model......appears in instances?...is used by other schemas? 2. Calculate dependencies: What else is needed to make things work properly? 3. Generate schemas Result: a set of schemas which validate consistently with the full schemas

5. Information Technology and Telecommunications Laboratory May 2005 Schema Subset? Instances that validate against the schema subset will validate against the full schema.

6. Information Technology and Telecommunications Laboratory May 2005 Step 1: Determine Requirements Determine what from the data model is required: What elements are used? What elements need to appear in what types? What types are referred to explicitly? What types are used in local schemas? What enumerations may be used?

7. Information Technology and Telecommunications Laboratory May 2005 Step 2: Calculate Dependencies A type requires:  Its base type  Its simple type  Any elements which may occur within  Any attributes which may occur within  Any facets which are required An element requires  A definition for the element  The object type of the element

8. Information Technology and Telecommunications Laboratory May 2005 Step 3: Results The schema generation tool generates a ZIP file containing all resulting schemas. These schemas may be used in place of the full GJXDM schemas. Requirements may be edited and the schemas regenerated.

11. Information Technology and Telecommunications Laboratory May 2005 Want List: Summary of requirements List of requirements Input for the schema generator Persistent record Versioning mechansim

13. Information Technology and Telecommunications Laboratory May 2005 Calculating Dependencies Rules are at http://justicexml.gtri.gatech.edu/rules_for_schema_subsets.html The tool does it for you!

14. Information Technology and Telecommunications Laboratory May 2005 Subset Schema Schema Subset tool generates a zip containing the full hierarchy of schemas:  Original: 47 files  Subset: 2 files jxdm/3.0.2/jxdm.xsd jxdm/3.0.2/proxy/xsd/1.0/xsd.xsd Subset is much smaller  Original: 8,180kb  Subset: 4kb Subset can validate in place of the full schema

15. Information Technology and Telecommunications Laboratory May 2005 Subset Schema Validation times greatly reduced:  Original: 4.01 seconds  Subset: 0.17 seconds Subset schema is comprehensible:  Original: 2570 pages  Subset: 1.5 pages

16. Information Technology and Telecommunications Laboratory May 2005 Summary The GJXDM Reference Schemas are very large A smaller subset of the full schemas may be used instead There are rules for creating subsets Requirements are important There are tools to assist selection and generation

17. Information Technology and Telecommunications Laboratory May 2005 SSGT Design Goals Provide a mechanism to get the pieces of the GJXDM that are desired Make the GJXDM more manageable Have multiple GJXDM release support No user accounts or passwords Similar to the GJXDM Model Viewer (searching functions and linked elements) Saving/Loading data to be able to make changes later

18. Information Technology and Telecommunications Laboratory May 2005 Menu Properties and Types from the GJXDM to be included in subset Search Form Add Properties or Types to subset Search Results
