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

Or to build and run

docker build -t mtas https://raw.githubusercontent.com/textexploration/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 74 million items for search and analysis as specified below.

	Total	Mean	Min	Max
Solr index size	2,715 G	60.3 G	75 k	288 G
Solr documents	74,762,559	1,661,390	119	11,912,415

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 44 separate cores. For 41,437,881 of these documents, annotated text varying in size from 1 to over 3.5 million words is included:

	Total	Mean	Min	Max
Words	18,494,454,357	446	1	3,537,883
Annotations	95,921,919,849	2,314	4	23,589,831
