Data Catalogs allow BI developers to share metadata and information about the data structures that users access when building or using analytical content. Pyramid self-builds a data catalog for all the models that can be accessed in the system - including those generated and maintained externally (like MS OLAP and SAP BW etc).
As a user hovers over hierarchies in the hierarchy tree, measures in the measure tree or either item in some visualizations, they will be able to see snippets of the data catalog in pop-up tool tips. This provides contextual, point-and-click access to the metadata surrounding an item in the data model. If descriptions and structural elements have been set inside the model, they will appear in the tooltip. If admins have used the overlay framework, to personalize the messaging for a user(s), that will be displayed instead.
An alternative way to access the ENTIRE data catalog for a given model is to export it to a PDF document.
To export the catalog, click the info button next the data source inside the Discover interface.
In the info dialog that pops-up, click the Data Catalog Export Button.
