[Medin_dacwg] Data Accelerator storage costs

[Postlethwaite, Clare]

Hi Ulric,
No MEDIN hasn't looked at storage costs in terms of the data accelerator project. As you know the MEDIN funding model is that the data funder pays to archive the data at a MEDIN DAC and the core funding capability of the DAC covers the storage etc (for the data that each DAC specialises in).

In terms of large files, UKHO are already serving their very large multibeam datasets so that should be ok (but UKHO would need sufficient warning to anticipate any significant numbers of datasets landing on their desks).

I believe the way that some of the DACs deal with serving large video files is to make a short section available for download so users can see if it is something that they are interested in and then the full dataset is available on request.

I'm copying  the DAC working group in case they have further comments on online access to large datasets like those you describe.
Best wishes,
Clare

Hi Clare,

As part of the MEDIN response to the data accelerator  / open data process has MEDIN looked at storage costs / types?

Obviously the ideal is for data to be accessible on a direct link - online storage - which is relatively expensive, especially if the data is video or multibeam and very large.

For large data types, how are MEDIN proposing to provide access and does Data Accelerator increase costs beyond the DAC archiving costs already in place?

Any thoughts welcome, as we're looking at all the MCZ video data and wondering if we _really_ need to have online storage for it (especially as many users would be put off by the file sizes anyway).
