AAS Heritage of Publishing Data AAS founded the Astrophysical Journal Supplement

in 1954 to publish the “data-rich” papers of the day. The move to electronic publishing (as the version of

record) ended the era of extensive typeset tables AAS journals currently accept machine readable

tables, FITS format, movies, and other VO-compatible formats.

AAS/AIP data access project1. Journals will extend the methods for providing access to

data objects2. Survey community attitudes about data sharing and re-

use3. Engage community in discussions about formats and

metadata

Responds to various calls for digital data curation and sharing EC: Riding the Wave (2010) UK/RIN: Collaborative Yet Independent (2011) US NSB: Digital Research Data Sharing and Management

Data sharing/attitudes survey

Conducted by AIP SRC 12/12 – 1/13 With NSF support

~1000 respondents in astrophysics and plasma physics (68% response)

Two main themes Use: requests, receipts, re-use Sharing: inquiries, deliveries Recently (past 2 yrs) and future expectation

SSP, May 2014

Data sharing survey62% shared in last two years58% expect to share in next two years

Plus 28% who said “possibly”60% have requested data in last two years68% expect to request in next two years

Plus 23% who said “possibly”Astronomers generally have no problems

with data sharing
