Apple Venue Format (AVF) Reader/Writer (IMDF)

Licensing options for this format begin with FME Professional Edition.

The Apple Venue Format (AVF) can be used to import indoor mapping data into Apple® Maps. FME supports both reading from and writing to AVF.

AVF is a fixed-schema format based on GeoJSON. Besides the schema, the specification defines a complex set of data content rules that must be met for AVF data to be considered valid. The specification and AVFValidator links referenced in Resources have more information about these requirements.

For more information about this format, see Creating AVF Files with FME.

Dataset Structure

An AVF dataset is a folder of GeoJSON files with one file per AVF feature type.

To read an AVF dataset, the user can select an AVF dataset folder, a zip file, or a venue.geojson file.

To make data exchange more practical, AVF datasets are often written using a .zip extension, which automatically creates a single zipped file containing the feature type GeoJSON files.

AVF datasets also contain a manifest.json file that specifies the file format version, creation date, and default language in the form of:

{
    "version" : "2.0.0.beta.2",
    "created" : "2018-07-04T23:28:35Z",
    "language" : "en"
}

The writer creates this manifest.json file automatically, based on the user's default language setting.

The AVF writer will reproject all features to WGS84 when they are written.
