Why versioning important?

• The water objectives are legally binding in Sweden

• 26 000 water bodies which are constantly being improved.

• Things do change• Reporting requirements• Protected areas• National objectives

Versions – more detailed at national level • National level WISS

• Classifications• Measures• Protected areas• Water bodies

• Reporting• Water bodies

Classificiations - exampleLogged in – see name of editors

Editable

Measures – life cycle and versions

Water bodies

Waters- Internal ID- Date registered

Contains all water internal IDs ever added to the database – marked by date

Main version- ID main version- Active/Not

After each delivery a main version is updated with the current ”active” water bodies

Part deliveryID main versionName delivery

version

A part delivery version is maintained for example:”Surface_water_2014_1” or”Ground_water_2014”

Water delivery- All ID:s- Name- Water Category- Drainage basins - etc

For each delivery the waters are registered in this table containing everything that can be changed for example name, drainage basin.The same water can be registered here several times if it have been in several deliveries but only once in the Main version

Versioning in reporting WFD a lot simpler!

Suggested amendments WFD reporting guidance • <TypeWaterBodyChanges>

• merged, split, both (original)• merged, split, both, new (change)

• <2010EUSurfaceWaterBodyCode> - lists!• Merged: Need to be 1:N• Split: OK• Both: N:N (very complicated to use – ignore?)• New: OK• Deleted: For QA of COM – suggest to report
