Hello,
Or working on new datastore providers.
Since we have the Feature and query API running I think it would be
great to have a GeoPackage provider.

Hello Kelsea, and welcome!
Looking at your experience, you seem familiar with indexing. Apache SIS
has a QuadTree index which is currently orphan. The index Java code is
located at:
storage/sis-storage/src/main/java/org/apache/sis/index/tree/
If you feel interested about working on an index system, we can make a
plan about what could be improvements to that code. It may be easier to
do that next week because Alexis Manin will be back from vacation and he
may have input on this topic. In the meantime, it may be worth to take a
look on QuadTree [1] and R-Tree [2] pages on wikipedia.
Alternatively, if you would like to try something new and have
inclination for mathematics, we still have some map projections to
implement [3]. This work is more "mechanical", with very specific
classes to extend and method to implement for each set of formulas. I
will expand more on this topic if there is an interest.
Another possibility is to continue the work on JavaFX components for
giving a Graphical User Interface to SIS (this work was started by other
students).
For information, Hao is doing a Google Summer of Code project which has
some similarities with your previous works. But instead than scanning
HTML files, Hao's work scans GeoTIFF, netCDF and some other geospatial
files. And instead of collecting words, Hao's work collects information
structured like a form, with a clear "title" field, an "author" field, a
"geographic extent" field, etc., which enable searches by title, author,
etc. If you feel interested in this topic, we can try to coordinates in
such a way that your work are complementary.
Do you have a preference for any of those alternatives?
