Difference between
version 2
and
version 1:
| Line 21 was replaced by line 21 |
| - * Developed a new algorithm for importing XML Schema files into the__internal schema trees in SCIA, based on Apache__XML Schema APIs and DOM 3 APIs, in order to acquire constraint__information and more useful type information for matching and mapping, and__also to support more__complicated XML Schema files, including EML. |

| - * Solve the memory issues with large size schemas which possibly contain recursive references. For example, currently, loading more than 1/3 of EML would cause OutOfMemoryError or StackOverFlowError, though 128MB is allocated for heap and 512MB for Java Virtual Machine (default only__64MB), 200MB for stack (default only 400k). The StackOverFlowError is caused by the recursive references in EML, e.g., A DataSet element has a subelement Methods, while a Methods element has a subelement DataSource of type DataSetType. __This issue reinforces that SCIA should be able to represent an input schema __ as a main tree and multiple sub trees, instead of a single schema tree. |
| - * Look for new free XQuery engine. There are two main reasons for this. __Firstly, the Quilt engine, Kweelt, which we are using now, uses a very old __version of xerces package that is not compatible with the new version that covers XML Schema __APIs. In addition, SCIA'd better generate view in standard XQuery, in order to easily work with other applications together |
