    3232The proposed SQLite provider will have the following features:
    3333
    34 * Data stored and consumed in native SQLite format, and therefore accessible to other SQLite-based applications;
    35 * Geometry will be serialized as BLOBs in FDO geometry format (FGF). Other ways that may be considered are storing points as X,Y columns and also geometry as WKB format;
    36 * A non-persistent, spatial index usable for BBOX queries built on the fly and valid for the duration of the FDO connection;
    37 * Execution of arbitrary SQL commands;
    38 * A metadata table where the geometry coordinate system is stored in WKT or EPSG form. In addition, PRJ files will be supported as alternative means of specifying a coordinate system when a metadata table is undesirable;
    39 * A tentative list of supported FDO commands : DescribeSchema, Select, SelectAggregates, Insert, Update, Delete, GetSpatialContexts, arbitrary SQL, ApplySchema, CreateDataStore;

    4141FDO features the provider will likely *not* support:
    4242
    43 * Feature class inheritance;
    44 * Geometry filters other than BBOX;
    45 * FDO Transactions -- but you can still manually execute BEGIN/COMMIT around other FDO commands;
    46 * Any other exotic feature you can think of.
