Salve a tutti, permettetemi questo necroposting...

Copio un paio di paragrafi che ho preso dal sito dell'OGC[0]:
/A GeoPackage is an open, standards-based, platform-independent, portable,
self-describing, compact format for transferring geospatial information. The
GeoPackage standard describes a set of conventions for storing the following
within a SQLite database:

vector features
tile matrix sets of imagery and raster maps at various scales
To be clear, a GeoPackage is the SQLite container and the GeoPackage
Encoding Standard governs the rules and requirements of content stored in a
GeoPackage container. The GeoPackage standard defines the schema for a
GeoPackage, including table definitions, integrity assertions, format
limitations, and content constraints. The required and supported content of
a GeoPackage is entirely defined in the standard. 

Since a GeoPackage is a database container, it supports direct use. This
means  that  data in a GeoPackage can be accessed and updated in a "native"
storage format without intermediate format translations. GeoPackages that
comply with the requirements in the standard  and do not implement
vendor-specific extensions are interoperable across all enterprise and
personal computing environments. GeoPackages are particularly useful on
mobile devices such as cell phones and tablets in communications
environments where there is limited connectivity and bandwidth. /

Se il mio inglese non mi inganna ne deduco che il GeoPackage sia un formato
dati si ma simile ad un DB. Mi riferisco in particolare alla frase "/Since a
GeoPackage is a database container, it supports direct use./".

Ho pubblicato un articolo poco fa[1] proprio sul GeoPackage e vorrei avere
dei chiarimenti.
