What is the purpose of a blob entry in a repository?

jwalter

Repositories apparently can hold .ioo/.md,  .rmp and .blob entries  - according to the source code.

From the source code it seems to me that the blob stuff (BlobEntry etc.) is not really used (yet).

What is the purpose of a blob entry in a repository? It apparently is related to the import binary data wizard in the GUI.

How can I retrieve data from a blob entry?

Can I access e.g. a CSV file if it is registered as a blob?

And if not, could I write a retrieve operator (e.g. for CSV files) taking blob entries as sources?

And if so would your White Paper about extending RM provide me with the necessary information how this can be achieved?

Hi,
this is currently reserved for internal use only, namely for realising reporting via RapidAnalytics. So it isn't described in How to Extend RapidMiner.
