Configuring Semantic Permissions

You configure the Semantic permissions so that the users on the EBO server have permissions to use Semantic.

The EcoStruxure Building Operation software supports a database solution for external storage of semantic information.

The semantic information is a contextual representation of a building that follows the Brick schema. It includes representation of building assets such as points, locations, and equipment.

The semantic information is configured in WorkStation, and the information is available in WorkStation and WebStation. The information is also available through EcoStruxure Web Services.

Semantic Database

EcoStruxure Building Operation uses a Sparql database, GraphDB from Ontotext, to handle semantic queries.

For more information, see Semantic Database .

Ontologies

Semantic is based on ontologies.

For more information, see Ontologies .

Semantic Data and EWS

The EWS metadata makes it possible to add semantic information to the EWS items, provided that the EBO object that is exposed by EWS is semantically described.

Semantic tagging is exposed using EWS.

For more information, see Semantic Data and EWS .

Licensing

You can use a limited number of queries in the Graph database without a license. To be able to use the Graph database to its full extent a license is needed.

If you use an GraphDB on another location than the EBO default location, you have to aquire a license.

Semantic Navigation

You can navigate the semantic database using search and filter.

For more information, see Semantic Navigation in WorkStation .

For more information, see Semantic Navigation in WebStation .

Configure EcoStruxure Building Automation System to use Semantic Tagging

Use this workflow to configure EcoStruxure Building Automation system to use semantics.

For more information, see Configure EcoStruxure Building Automation System to use Semantic Workflow .

Semantic Engineering

Semantic engineering is the process describing an EcoStruxure Building operation database using semantic s .

For more information, see Semantic Engineering Overview .

Tenant Repository

You can create a semantic repository for each tenant. You do this in a system with multi tenants where you do not want the tenants to share their semantic information.

For more information, see Tenant Repository .

Note:

The Semantic Admin permission does not exist in older version and is not inherited to a sub-server with older version. To be able to engineer semantics on sub-servers of 4.0 you must set the semantic permission rights to “Write” on the group or you must create groups directly on the sub-server with Write permission.

To configuring semantic permissions

  1. In WorkStation, in the System Tree pane, select the EcoStruxure BMS server.

  2. Click the Control Panel tab.

  3. Click Account management .

  4. In the Server list, select the EBO server containing the user account group.

  5. In the Domain list, select the domain the user account group belongs to.

  6. In the User Account Groups list, select the user account group.

  7. Click Policies .

  8. In the Semantic permission list, select the permission for the group.

  9. Click Save .
