Long descriptions

[rweigel]

A soon-to-be released website that allows search of Heliophysics data will use the content of our nightly aggregation of all HAPI metadata (or a reduced version). The website developer noted that they like to display a long description of a dataset, but we generally only have titles or short descriptions. We may want to consider developing a "patch" that has a long description (in collaboration with data providers and for certain datasets where this is feasible) that can be used until data provider updates their server's metadata.
