special data node type for mca
after discussing with @sole it seems like we are missing a good, build-in way to filter mca data nodes when listening to redis. There were three ideas around:
- allow filtering by
shape
during thewalk
- introduce a new data node type specifically for mca, so that one can use the existing filter mechanism
- add an
interpretation
property to the data note which could as well be used to keep the Nexus h5 attributeinterpretation
somewhere.
