ADASS BoF: Implementing Ideas for Improving Software Citation and Credit

On Tuesday at ADASS, ASCL Advisory Committee Chair Peter Teuben led a Birds of a Feather session intended as a working session to have people put some of the ideas for improving software citation and credit into practice.

ADS now has a doc type called software

Slide from Peter’s opening presentation

He opened the session with a few remarks about last year’s BoF, similar efforts elsewhere, and examples of progress since last year. Yes, there has been progress! He then showed a list of actionable items and asked people to work on them, adding their work to a common Google doc. His slides are here.

And they did! It was the quietest BoF ever, I believe, as Keith Shortridge, Bruce Berriman, and Jessica Mink wrote about their experiences in releasing software; Renato Callado Borges and Greg Sleap provided guidance on the types of software contributions that add value to science; Alberto Accomazzi, Nuria Lorente, and Kai Polsterer listed ways one can publish and take credit for software; Peter Teuben, Steven Crawford, and possibly others pulled together a list of organization web pages about software created at the institutions, this as a way to highlight and recognize scientific software contributions; Maurizio Tomasi added a suggestion for gathering licensing information; and Thomas Robitaille, Ole Streicher, Tim Jenness, Kimberly DuPrie, and I discussed exactly what should be in the “Preferred citation field” of the ASCL and various people listed about a dozen preferred citations to be added to the ASCL and others used the Suggest a change or addition link for several software packages to provide preferred citation information.

Though Peter had asked that people work for about 30 minutes, he monitored contributions to the Google doc and saw work was still being done so did not call us back together until only 15 minutes or so were left in the session. Instead of having people report back on what they had done as originally plan, he asked for other feedback instead, as progress made was evident in the shared document, and after a bit of discussion on licensing and a few other comments, closed the session.

Though the session is over, the next phase is to put this information to use or disseminate it in some way so it can do some good and be the changes we want to see for software!


ADASS XXVI poster: Decoupling the Archive

Decoupling the archive posterThe James Webb Space Telescope (JWST) archive will store numerous metadata for the various files that it contains: at the time of this writing a single FITS file can have up to 250 different metadata fields in the archive, most of which map to keywords in the primary header or header extensions. One of the goals of the archive design is to allow for changes to the fields stored in the database without having to change the ingest code. We have found this to be very helpful during the code development phase of the mission when the FITS file definitions are frequently changing. We also anticipate it will be advantageous during the lifetime of the mission as changes to processing will likely result in changes to the keywords but should not require changes to the ingest code. This poster describes the methods we use to decouple the archive from the ingest process.

Birds of a Feather session at ADASS on software citation and credit

The Implementing Ideas for Improving Software Citation and Credit BoF is intended to be a working session to put ideas already generated into action! Everyone in the community has a role in improving it. We have listed a lot of ideas in the previous post about this BoF, have slides online here, and a Google doc to which you can contribute here.

Montage poster at ADASS 2016

We want to share some of the posters that are appearing at ADASS this week (with permission of their authors). Montage is in the ASCL; we love this poster for several reasons, but especially because it makes clear that sustainability of the software is important!

Abstract: The Montage toolkit is finding exceptional breadth of usage, far beyond its intended application as a mosaic engine for astronomy. New uses include:
– Visualization of complex images with data overlays: e.g. as a re-projection engine integrated into the server-side architecture of a Gbit visualization system supporting investigations of 3D printing with the X3D protocol creation of sky coverage maps for missions and projects bulk creation of sub-images of multiband photometry data creation of plots in the APLPy library.
– Creation of new data products at scale: mosaics of Gemini AO images from the Gemini Multi-Conjugate Adaptive Optics System/Gemini South Adaptive Optics Imager (GEMS/GSAOI) instrument, from the VISTA VIDEO and the UKIDSS DXS surveys welding the Herschel infrared Galactic plane (Hi-GAL) far-infrared Survey into a set of large-scale mosaics, for planetarium shows at a digital as well as for research
– As a re-projection engine to support discovery of 86 Near Earth Asteroids (a U.S. congressional mandate) in the Lincoln Near-Earth Asteroid Research Program (LINEAR).
– Integration into data processing environments: integration of the 4D image cutout tool into the VO-compliant CSIRO ASKAP Science Data Archive (CASDA) as a re-projection engine for the Dark Energy Survey (DES) pipeline.
– Discovery of imaging data at scale: use of memory mapped R-tree indices to support searches for spatially extended data, in use in Spitzer and WISE image searches and in spatial and temporal searches for WISE and KOA.
It has been cited as an exemplar application for development of next generation cyber-infrastructure in 238 papers between 2014 and 2016 to date. What has enabled this broad take-up is that Montage has been built and managed as a scalable toolkit, written in C and portable across all common *nix platforms, with minimal dependencies on third-party software, such that it can be built with a simple “make” command. All the components have proven powerful general-purpose tools in their own right, even those first developed to support mosaic creation, such as discovery of images for input to the engine and for management of mosaics. We describe how Montage is managed to assure that the benefits of the architecture are retained, and how we ensure that new development is driven by the needs of the community.


ASCL poster for ADASS XXVIThe Astrophysics Source Code Library (ASCL) is a free online registry of codes used in research; it is indexed by ADS and Web of Science and has over 1300 code entries. Its entries are increasingly used to cite software; citations have been at least doubling each year since 2012, and every major astronomy journal accepts citations to the ASCL. Codes in the resource cover all aspects of astrophysics research and many programming languages are represented. In the past year, the ASCL has added dashboards for users and administrators, started minting DOIs for codes it houses, and added metadata fields requested by users. This presentation covers the ASCL’s growth in the past year and the opportunities afforded to it as one of the few domain libraries for science research codes, and will solicit ideas for new features.

The Astronomical Data Analysis Software and Systems (ADASS) conference starts today in Trieste, Italy with two tutorials, Everything you’ve heard about Agile development is wrong by Simon O’Toole and Multi-dimensional linked data exploration with glue by Thomas Robitaille, and then the opening reception.

The ASCL has two activities at ADASS this year. I’m presenting a poster on the ASCL’s growth over the past year; the poster will be featured in a separate blog post tomorrow. On Tuesday, Peter Teuben, chair of the ASCL Advisory Committee, and other ASCLers here are running a Birds of a Feather session on Implementing Ideas for Improving Software Citation and Credit; this is a follow-up of last year’s session on Improving Software Citation and Credit. This year, we will look at some of the ideas that came out of last year’s session along with ideas generated at the Engineering Academic Software seminar held in June, 2016 and WSSSPE4, held last month at the University of Manchester, and work to implement them. These ideas include:

  • collecting and publishing stories from people who have released their software to share their experience with doing so
  • updating software sites you own to explicit state how your software should be cited
  • emailing code authors who don’t have clear citation instructions on their repos/code sites to suggest they make clear how their codes should be cited
  • adding preferred citation methods to ASCL entries via the “Suggest a change or addition” link or sending them to associate editor Kimberly duPrie or me to add directly
  • looking at your organization’s annual research activity report and suggesting ways it can specifically request software activities
  • writing a document that provides guidance about the types of software contributions that add value to science
  • developing guidelines for recognizing software contributions in hiring and promotion
  • gathering representative research software engineering job descriptions and adding them to the AstroBetter wiki, and suggesting other ways they can be shared for use them as examples

We look forward to an interesting and productive BoF, and an interesting and productive ADASS overall. And gelato, too!

Upcoming events and sessions, Fall-Winter 2016/7

I’ll be representing the ASCL at next month’s WSSSPE4 meeting in Manchester, and in October, the ASCL will be at ADASS XXVI and will hold an Advisory Committee (AC) meeting while there. Peter Teuben, chair of the ASCL AC, will moderate a Birds of a Feather session at ADASS on Implementing Ideas for Improving Software Citation and Credit; this is a follow-up on the discussion at last year’s BoF Improving Software Citation and Creditwith a goal of taking action on some of the ideas generated at last year’s BoF. Watch this space in October for more!

For January’s American Astronomy Society meeting in Texas, the Moore-Sloan Data Science Environment at NYU and the ASCL have organized another Special Session, Perspectives in Research Software. This will follow the format of previous sessions, with presentations in the first half of the session and discussion open to all for the second half. Bruce Berriman from the Infrared Processing and Analysis Center at Caltech will moderate; the presenters include Ivelina Momcheva (Space Telescope Science Institute),  Tracy Teal (Data Carpentry), Lior Shamir (Lawrence Technological University), and Michael Hucka (Caltech). I’m rationally exuberant about this session!

Improving Software Citation and Credit BoF session slides

On Tuesday, October 27, the ASCL held a Birds of a Feather session at ADASS on Improving Software Citation and Credit. The session was opened with a brief presentation by Bruce Berriman, who reported on a Software Publishing Special Interest Group meeting held at the January 2015 AAS meeting and the ongoing work that has come out of that. I followed with a quick overview of other efforts to improve software credit and citation, not just in astronomy but across disciplines, after which Keith Shortridge moderated a lively discussion among the forty people present. The slides Bruce and I presented are now available online.

Previously, we shared resources for the session and the Google doc created during the session to capture some of the main points from the discussion.

Some of the posters, some of the codes

I used to read ADASS posters in part to find new codes to register. I still do that, but it’s harder these days, for reasons that make me very happy: many of the codes are already in the ASCL! Here is a sampling from a quick and definitely not thorough perusal of posters.

CIGALE [ascl:1111.004] and LePHARE [ascl:1108.009]
PySALT [ascl:1207.010]
SoFiA [ascl:1412.001]
Splotch [ascl: 1103.005]
TOPCAT [ascl:1101.010]
Vissage [ascl:1402.001]

It’s lovely to see ADASS folks I’ve met before, and lovely to see codes I already know. It’s also great to meet new people and run across new codes, and I’ll be highlighting some of the new codes added as a result of this ADASS in a future blog post.
