Requesting Complete Specification of conf.xml #2

Open FilmCoder opened 6 years ago

FilmCoder commented 6 years ago

Hello!

You give a brief overview on the structure of the conf.xml inside compact caches. Is there however a complete specification available? For example, what are the exact possible values, tags, namespaces, texts, order of precedence between fields, etc...?

For example, the readme does not even mention what might preside inside the SpatialReference tag.

This spec is necessary so other pieces of software can be built inter-operable with arcgis, such that other programs can read compact caches created by arcgis, and write compact caches which can be read by arcgis.

Also, a spec is requested for the conf.cdi!

Thank, Dom

@FilmCoder ,

You can get details on Spatial Reference at https://developers.arcgis.com/documentation/core-concepts/spatial-references/ and extents at https://developers.arcgis.com/documentation/core-concepts/features-and-geometries/#extents.

We are working on making the specification for conf.xml and conf.cdi available.

Thanks, Garima
