 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]]. With meta-data, we identify all data that surrounds a slide, but that is not graphical.

 +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:
 +
 +^ Meta-data ^ Location ^ Storage ^
 +| Intrinsic meta-data | Embedded in the slide'​s [[supported_file_formats|file format]] | File system or cloud FS |
 +| User-captured meta-data | Stored in PMA.core | PMA.core RDBMS (SQLServer) |
 +| External meta-data | Stored in own (customer) database | SQLServer or Oracle |
 +
 +==== Intrinsic meta-data ====
 +
 +This type of data can be consulted via the Image Management'​s [[image_manager#​slide_view_right_panel|left panel]], or more directly via the [[interfacing_the_server_from_3rd_party_software|API]].
 +
 +==== User-captured meta-data ====
 +
 +In the [[form_management|forms management section]], data input forms can be designed that are subsequently assigned to virtual slides. These forms can then be filled in by the system'​s users while viewing slides. The data that users submit for each form are also available within this section.
 +
 +==== 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: ​
 +
 + * first, you define the link to the resource (via a connectionstring). In PMA.core 2 this can be a SQLServer or Oracle RDBMS.
 + * second, you define a query that retrieves the data from the RDBMS, and identify a way so that individual records can be mapped back to specific filenames.
