Taking as a reference public documentation (https://wirecloud.conwet.etsiinf.upm.es/slides/1.2_Integration%20with%20other%20GEs.html#slide16) I wonder if at this point there is any progress on connecting Wirecloud & Cosmos in order to retrieve historical data and visualised it over mashups setups.
If not, could you give any direction so I can give a try implementing something around this?
Note: I have already checked some of the available documentation, and it looks to me that my desired feature could be tackled by a simple python implementation to retrieve HDFS files to the appropriated NGSI format, Is it right?
Nevertheless, I believe it will be a dirty mechanism. What should be the recommended way?
I honestly hope not to be cheating by answering my own questions and marking them as correct, but I would like to leave a record of a solution for those folks that might be experiencing same troubles as me.
I have developed a quick and dirty mechanism to retrieve HDFS files into NGSI formats so we can retrieve historical data like we do with Orion widgets.

Please note, that this is a quite working progress, so there are some hardcode that I hope eventually fix.
