Last few weeks:
- Added a few features to Exhibit, including
- Functions and operators in expressions
- Support for multiple hops in facet definitions
- Exhibit-ized a few data sets.
- Added aggregate functions (MIN, MAX, COUNT in conjunction with GROUP
BY) to Sesame2's query model and provided an implementation for the
memory store and the native store.
- Submitted a patch to Sesame2 for optimizing literals containing Java
native types (int, long, double, boolean, ...). There is a little bit of
performance gain for the memory store and the native store on queries
that contain math expressions.
- Made progress on openrdf-sail-mysql (sesame2 over mysql).
- Performance gain (over memory store) ranges from 7 fold to 75 fold
on aggregate queries for 50K triples.
- Wrote thesis outline.
- Thought a bit about Potluck, the last engineering piece of my thesis
puzzle.
This week:
- Support ex:if, ex:select in Exhibit's lens templates.
- Focus on Potluck.
- Help someone take over openrdf-sail-mysql.
Long term:
- Break up Exhibit's UI into more pieces to enable more flexible layouts.
