Custom data format, possible?

Hello,

Is it possible to create a new data format in addition to the ones natively supported by HoloViews? The project I work on uses the casacore table format. This data data format is open, but it is pretty niche. It is basically a tabular data storage system for what is probably medium sized data these days (say tens of GB). It has a python interface to access the rows and columns.

Is there a way to allow HoloViews to access this data directly or does it have to be completely read in and stored in one of the supported data formats?

Thanks very much for any advice!
