Re: [Kexi] [ideas] GIS in Kexi; was: Google Fusion Tables - storage for Kexi?
I like to put these things into perspective. This is the hierarchy: - GIS - Spatial - Map I think Spatial in Kexi can be easily done using Spatialite. It is - Sqlite3 + the geom (geometry column added in Sqlite3 file). Once Kexi can accept (write and read) raw Sqlite3 files (i.e. .db and .sqlite), it just adding the geometry column (e.g. geom or geometry) in the table. GEOS, Proj4 are dependent libraries for Spatialite. Jaroslaw, I think can we probably propose a GSOC for SQLite3 for Kexi. It seems that since 2007 Kexi users need read and write access for SQLite3 in Kexi. Any comments? Thanks.

Re: [Kexi] [ideas] Google Fusion Tables - storage for Kexi?
I feel no surprise MS Access is somewhat 'aside' of such developments: it allows either for embedding ActiveX elements or binding to custom data via degraded ODBC interface. So few points where integration/extensibility is possible... Here are some thoughts about MS Access and QGIS. http://gis.stackexchange.com/questions/9462/can-qgis-read-an-odbc-connection Things being discussed above also applies to Kexi usability outside Kexi GUI.

[Kexi] Re: Kexi selected for Google Summer of Code!
Hi Jaroslaw, Reading this note[1], it seems that you want to use OSM for Kexi marble widget you can use OSM sqlite3 database file and MBTiles [1] http://community.kde.org/Kexi/Junior_Jobs/Map_Browser_Form_Widget/Log-2011-04-08 Sqlite3 database for offline: a) OSM sqlite3 - OSM Tiles (i,e, map2sqlite) http://www.gisnotes.com/wordpress/2010/08/iphone-dev-note-21-route-me-offline-mapping-from-database/ b) MapBoxTiles (MBTiles) https://github.com/mapbox/mbtiles-spec See sample project of MBTiles in https://github.com/mapbox/route-me Importer and Exporter of MBTiles https://github.com/mapbox/mbutil You can easily make Mapbox Maps using TileMill http://mapbox.com/#/ BTW, Spatialite has support for projection and GEOS. Supporting spatialite / sqlite3 database in Kexi will make things easier to implement more sensible marble widget in Kexi. Here's the changelog of spatialite RC-4. http://www.gaia-gis.it/spatialite-2.4.0-4/changelog.html RC-4 [2010-11-14] * libspatialite o completely refactored CSV/TXT reader o now supporting KML and GML geometry output [AsKML(), AsGml()] o introduced a new SQL function supporting easy WGS84 POINTs filtering: PtDistWithin() o fixed several memory leaks (mainly related with the new WKT parser introduced in RC-3) o fixed some bugs o major updates to the build scripts o update: SQLite v.3.7.3 [introducing Geometry Callbacks support: RTreeIntersects(), RTreeWithin(), RTreeContains(), RTreeDistWithin()] http://www.gaia-gis.it/spatialite-2.4.0-4/index.html Thanks.

What do you think about me blogging my way of the Calligra developer? This would be technical, high level view about the source, and thinks that I found hard to understand or interesting, maybe this would be helpful for somebody? Hi Radek, No doubt it will be helpful! Just make sure your blog is syndicated at http://planetkde.org/ before you blog. Regarding the data types, it's hard to add it in current kexi, since kexidb is feature-frozen. Predicate is not but it's in heavy development (refactoring) and I wouldn't like to destabilize it. I am not 100% sure about the use case. If you mean adding lines, points and polygons to the map (by the user), I would recommend using some predefined XML (first define it on a wiki page). In any kexi database there's kexi__objectdata table where you can save extra data string related to any object (here: form and report). Query objects use that to store SQL statements and forms use it to store QtDesigner-like XML for UIs.
