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)

This Version

With version 0.3 the timeseries tables was completely refactored. This table is now using an ARRAY data-type and can store more than one value per record. To keep track of the actual data, the Datasource model now stores the names of each element and the Detail is using a JSONB data-type to store nested details. This way, multiple informations can be referenced by the data names to attribute metadata to only a part of a record.

This Version

With version 0.2.10, the Person model has been enhanced. Now, persons receive a UUID and will be queryable by this UUID from outside in a future version.
Secondly, a spatial filter is implemented. With this version, an Entry can search for other metadata entries within a search radius. For more advanced spatial queries, the metacatalog.util.location sub-module can create sophisticated search shapes from a variety of input arguments.

• keyword that is used to tag the entry
• detail - custom set of additional information

This Version

Verison 0.2 made substantial changes to the database schema. With 0.2, it is in principle possible to store all mandatory and most of the optional metadata, that is required by ISO 19115 / INSPIRE. The only missing objects are DQ_DataQuality and the Measurement & Observations scheme for measurements.
An export extension and the missing tables will be added with version 0.3.
