 ===== Meta-data =====
-With meta-data, we identify all data that surrounds a slide, but that is not graphical. The actual pixels (or viewport representation) of a slide are //not// meta-data. [[working_with_annotations|Annotations]] can be considered meta-data in the semantic sense, but they're link to graphical activities as well. So [[working_with_annotations|annotations are discussed elsewhere in this manual]].

 There is [[https://realdata.pathomation.com/how-to-handle-slide-meta-data/|a blog article]] that serves as a complementary tutorial to this blog entry. In [[https://realdata.pathomation.com/how-to-handle-slide-meta-data/|the article]], we consider 3 types of meta-data in PMA.core:

 ==== External meta-data ====
+No matter how powerful we make our own [[form_management|form management]], we realize that there will always be external data silos that for any number of reasons are inconvenient to bring to PMA.core in their entirety.
+That's why we provide the option to [[external_data|establish links to external databases systems]] in a two-step fashion:
+  - You define the link to the resource (via a connection string). In PMA.core this can be a SQLServer or Oracle RDBMS.
+  - You define a query that retrieves the data from the RDBMS, and identify a way that individual records can be mapped back to specific filenames.
+Furthermore, PMA.core can be configured to [[external_api_data|fetch JSON formatted data from external APIs]].
