    3030Currently FDO OGR provider is available in FDO open source website, which provides capability to read MapInfo .TAB and .MIF/.MID files. However, it has the following major limitations.
    3131Supports reading only.
    32 * Not support FdoISelectAggregates command.
    33 * Support very limited expression.
    34 * Support limited spatial/non-spatial filter.
    35 * Cannot handle coordinate system correctly.
    36 * Support limited data type.
    37 * Support limited geometric type.
    38 * ……

    3941FDO MapInfo provider is to create an FDO provider for MapInfo .TAB and .MIF/.MID files to eliminate the limitations above and provide reading/writing capability for .TAB and .MIF/.MID files.

    4345FDO MapInfo provider is implemented based on MITAB library (http://mitab.maptools.org/), which is an Open Source C++ library to read and create MapInfo .TAB and .MIF/MID files. It is based on the OGR library which is an implementation of the Open GIS Consortium Simple Feature specification.
    4446However, MITAB can’t meet all requirements of FDO MapInfo provider. For example,
    45 * MITAB doesn’t support update and delete a feature.
    46 * MITAB doesn’t support some of FDO data type such as boolean and decimal. But .TAB and .MIF/.MID files really support them.
    47 * ……

     48    * MITAB doesn’t support update and delete a feature.
     49    * MITAB doesn’t support some of FDO data type such as boolean and decimal. But .TAB and .MIF/.MID files really support them.
     50    * ……

    4852So we need to extend MITAB so that it meets our requirement.

    4954Now you can find development version of this provider in Google Code.
