-Meta tags are used to perform various aggregations and calculations in order to retrieve results for statistical analysis or user presentation. Alarm analysis meta tags allow A&data KPIs to be queried and visualised just like any process data source. View a full list of KPIs and detailed information on how to use meta-tags [[ https://github.com/intelligentplant/IAS-Power-BI-connector |here]]+The KPIs and metrics that make up the Alarm Analysis reports can be queried via //meta tags//, meaning Alarm Analysis data can be queried and visualised just like any other process data source. A good example of this is Power BI, where you may wish to create a bespoke Alarm Analysis report combined with other data sources.
  
 +For a full list of meta tags, refer to the [[https://github.com/intelligentplant/IAS-Power-BI-connector|Industrial Connector Help Page]]
 +
 +**Not all Meta Tags are Discoverable**
 +
 +While Power BI allows free text entry when configuring data queries, others apps such as Gestalt PnID and Trend restrict users to a "search and select" dialog. Generally, this makes UI interaction simpler, however "meta tags" are not constructed like regular tags and may not be available for search. Some meta-tags are dynamic and hold parameters which are interpreted by the Alarm Analysis data source. 
 +
 +For example,
 +
 +  Oil Co/Osprey/ALM BA report/3.priority
 +  
 +This above meta tag requests the priority of the 3rd most frequently occurring Alarm on the Oil Co Osprey asset. Clearly this is not a value you would expect to interrogate like a regular process data tag, however there may be cases where it is required.
 +
 +If explicit tag entry is not permitted in an app, and the meta-tag is not available in search, it can be manually added to the Alarm Analysis Tag Index. For more information, refer to: [[alarm_analysis:How to add a "Meta Tag" to an Alarm Analysis Tag Index]]
