See meertensinstituut.github.io/mtas/ for more documentation and instructions.


A docker image providing a Solr based demonstration scenario with indexing and querying of some sample documents is available. To pull and run

docker pull meertensinstituut/mtas
docker run -t -i -p 8080:80 --name mtas meertensinstituut/mtas

Or to build and run

docker build -t mtas https://raw.githubusercontent.com/meertensinstituut/mtas/master/docker/Dockerfile
docker run -t -i -p 8080:80 --name mtas mtas

This will provide a website on port 8080 on the ip of your docker host with more information.


One of the primary use cases for Mtas, the Nederlab project, currently1 provides access, both in terms of metadata and annotated text, to over 15 million items for search and analysis as specified below.

Total Mean Min Max
Solr index size 1,146 G 49.8 G 268 k 163 G
Solr documents 15,859,099 689,526 201 3,616,544

Collections are added and updated regularly by adding new cores, replacing cores and/or merging new cores with existing ones. Currently, the data is divided over 23 separate cores. For 14,663,457 of these documents, annotated text varying in size from 1 to over 3.5 million words is included:

Total Mean Min Max
Words 9,584,448,067 654 1 3,537,883
Annotations 36,486,292,912 2,488 4 23,589,831
