✨Data Dashboard

 Once a metadata file has been processed against a lexicon of choice, MaRMAT v 2.7.0-p includes an additional option in the Perform Matching screen – a Load Statistics button (screenshot at right).   By clicking on this button, users can view the data dashboard which includes topline statistics on your report and four data visualizations.

✨Data Visualizations

Powered by Pythonl libraries matplot lib and wordcloud, there are now four built-in data visualization graphs that will provide high-level assessment of reporting files. See below examples. These include:

  1. Category Distribution –  provides term hits by lexicon category.
  2. Top 10 Most Frequent Terms – chart of most frequently found terms in uploaded metadata file from lexicon with terms’ lexicon categories noted by color.
  3. Metadata Column (element) Hit Distribution – this report is helpful if you are analyzing multiple elements in one assessment report to see which element has the most flagged terms.
  4. Word Cloud on most frequent terms – this visualizes terms flagged with size of word indicating amount of times it appears in reporting with larger sized words indicating most frequently flagged in metadata.
Example Data Visualizations:
Example horizontal bar chart illustrating Top 10 Most Frequent Terms in this order: indians, indian, pioneer, native americans, plantation, daughter, wife, nazi, famous, and suspect. Each bar is colored based on the lexicon category the term is from.
Example Pie Chart comparing metadata elements (columns in metadata file uploaded) with count of terms found from the lexicon in each element.

✨Collection Title Reporting Addition

In the Configure Analysis screen, users can opt to include a Collection Title by clicking on the button, then select which column in the uploaded metadata file to represent the Collection Title via the  dropdown menu below the button (screenshot at right). 


This feature will be helpful when assessing large batches of metadata containing multiple collections. The output report can be filtered or grouped by collection title to aide reparative processes.

✨ Codec Compatibility 

Version 2.7.0 includes a patch update (2.7.0-p) to allow for files with codec in spreadsheets to be uploaded and processed by MaRMAT. This will prevent for uploading errors with data files containing encoded codec that can be difficult to identify and cumbersome to remove from data files.

✨ Lexicon Updates

There were a few minor updates to the provided lexicons. Updates by lexicon include:

  • Reparative Metadata Lexicon: Moved previous Incarceration Terms category to a more robust Criminal Justice Terms category – thanks to community feedback.
  • LCSH: Updated Problem LCSH category with latest list (as of July 2026)from Cataloging Lab’s crowdsourced Problem LCSH effort. 
  • Sensitive Content Lexicon: Added several terms to the Indigenous American Sensitive category
