Why don't we already have an Integrated Framework for the Publication and Preservation of all Data Products?

Why don't we already have an Integrated Framework for the Publication and Preservation of all Data Products?   Alberto Accomazzi,et al. Astronomical Data Analysis Software and Systems.

Astronomy has long had a working network of archives supporting the curation of publications and data. There are examples of websites giving access to data sets, but they are sometimes short lived.  "We can only realistically take implicit promises of long-term data archival as what they are: well-intentioned plans which are contingent on a number of factors, some of which are out of our control." We should take steps to ensure that our system of archiving, sharing and linking resources is as resilient as it can be.  Some ideas are: 

1. future-proof the naming system: assign persistent data IDs to items we want to preserve 
2. provide the ability to cite complete datasets, just as we can cite websites
3. include a data reference section in academic papers

Curated datasets need to be preserved indefinitely for scholarly purposes.
