We’re proud to announce the latest release of tDAR (Munsell).  This release was focused on modernizing and re-designing tDAR’s Data Integration tool to make it easier to use and faster, but also has a number of major feature updates across the application.

Completely re-designed data integration tool:
For those unfamiliar with tDAR’s integration tool, it provides a means by which users who have uploaded data sets to tDAR can combine multiple data sets with different schema and coding conventions into a unified, shared data set. 

We’ve redesigned it to simplify the user-interface.

Adding data sets is simpler.
Users can search for data sets that are bookmarked or integrate-able (that is, having one column mapped to an ontology), as well as  by keyword.

selecting tables

It is easier to add integration columns via a drop-down menu.

selecting an integration column

Once data sets have been added, if they share a mapping to an ontology, users can add an “Integration Column.” Integration columns allow users to further filter the resulting data set by selecting terms.

Once an integration column has been created, users can then "filter" results by selecting values from the ontology. tDAR display's a checkmark where each data set has actual values.

A new “count” column type that represents count data in data sets.

We’ve added better documentation of the integration in the excel output.
