VForWaTer/metacatalog: Version 0.4

About

Metacatalog is a management tool for a PostgreSQL/PostGIS database that is primarily used to store meta-data of environmental open data. While it can also store the data itself, it is more meant as a Meta-database that should rather interface the original data stores.

Metacatalog has three main submodules:

• the Database Models
• a Python API
• a CLI

The full documentation can be found at: https://vforwater.github.io/metacatalog.

This Version

With version 0.4 the API interoperability has been improved. This release mainly focuses on ImmutableResultSets, which can now lazy load Composite and Split datasets. Secondly, a large extension was added to metacatalog and activated by default: ExportExtension. It adds an export function to Entry and EntryGroup. The extension can export into files or return the underlying Python representation. The current supported export formats are:

• JSON (Python json str)
• XML (Python xml str)
• pickle (Python dict)
• netCDF (Python xarray)
