Document S1. Extended Discussion, Two Figures, and Supplemental References (PDF 534 kb)

6 What is in the Pandora’s box? Multimedia Chemical structures, crystallographic structures, 3-D images, gene sequences, protein structures Computer programs (algorithms, code, libraries, and executables) Tables, Figures, Text (Experimental procedures, Extended methodology, Survey results, Derivations, Extended bibliographies, …) Datasets (datasets are not the focus of this group) Seattle, WA 20 May 2012CSE 2012 Annual Meeting 6

7 Supplemental materials: good idea Enabling technology makes it possible for: authors to present supporting evidence, e.g., multimedia, data sets, computer programs; researchers to reveal in-depth studies that would not be available in print; readers to replicate experiments and verify results. Seattle, WA 20 May 2012CSE 2012 Annual Meeting 7

8 Questions to ponder Seattle, WA 20 May 2012CSE 2012 Annual Meeting 8 Degree of importance. Are all supplemental materials equally important? As a busy editor, reviewer, or reader; which ones must I focus on? Discoverability. How do I (librarian, indexer) know the article has supplemental materials? (Deadbeat parent) Identification. How do I know which article is the parent of orphaned / abandoned supplemental materials? Citing and linking. How do I provide a persistent link to the supplemental materials, and how do I cite them?

9 Questions to ponder (cont’d) Seattle, WA 20 May 2012CSE 2012 Annual Meeting 9 Viability and preservation. Will it be possible to render (read, play, execute, etc.) sup. mat. in 20 years? 200 years? It is likely that sup. mat. will have to undergo periodic migration. Then, do I look at the original or the converted object? Are they equivalent? Transmission and packaging. When fulfilling an interlibrary loan request or transmitting sup. mat. to an archive, how do I package them with the article? How do I ensure that nothing was lost or corrupted?

10 Questions to ponder (cont’d) Seattle, WA 20 May 2012CSE 2012 Annual Meeting 10 Intellectual property rights. Who has rights over sup. mat., and where are they recorded? Curatorial responsibility. Who has custody over sup. mat.: author, publisher, library, data center, institutional repository, archive, any other actor? Business models. If someone is going to provide peer review, identification, description, linking, preservation, and maintenance of sup. mat’s, what sustainable business models could support the expense?

11 Who cares? You should – if you … … play a role in the scholarly communication process as an: Editor / Reviewer / Author / Reader Publisher Hosting platform / Institutional Repository / Data center / Individual A&I service Reference linking and Citation indexing service Librarian / Archivist / Historian of scholarship Seattle, WA 20 May 2012CSE 2012 Annual Meeting 11

12 Researcher community response One camp: More supplemental materials should be made available! Technology will solve most problems! The other camp: Scholarly journal is not a data dump! An article is not an FTP site! Seattle, WA 20 May 2012CSE 2012 Annual Meeting 12

13 Publisher community response 2009: Cell imposes limits on the number and kind of supplemental materials accepted 2010: The Journal of Neuroscience bans supplemental materials altogether; intends to embed dynamic content in its articles’ PDF 2011: The Journal of Experimental Medicine limits supplemental materials only to "essential supporting information" Seattle, WA 20 May 2012CSE 2012 Annual Meeting 13

15 NISO / NFAIS Working Group Seattle, WA 20 May 2012CSE 2012 Annual Meeting 15

16 Supplemental materials: Pseudo vs. truly Print model: article layout implicitly reflected functional distinction between essential and nonessential objects (body vs. appendix) Mixed electronic-print model: both essential and nonessential objects are often treated as “supplemental materials” – yet, some are NOT Is the material essential or not? This must be stated explicitly for machine and human reader Seattle, WA 20 May 2012CSE 2012 Annual Meeting 16

17 Dimension 1: Importance Integral (“pseudo-supplemental”) Essential for full understanding of work but treated as if it were supplemental. Rationale: technical, business, or logistical limitations Additional (“truly supplemental”) Not critical for understanding the work. Relevant and useful – but still optional The distinction is conceptual and has NOTHING TO DO with formats Seattle, WA 20 May 2012CSE 2012 Annual Meeting 17

18 Dimension 2: Custody Publisher Recommended practices offered Institutional repository or Data center The publisher has no responsibility or authority over content and does not host it. No recommended practices offered Individual Not appropriate for hosting supplemental materials Seattle, WA 20 May 2012CSE 2012 Annual Meeting 18

19 Supplemental materials classification Importance Curated by IntegralAdditional PublisherRecommended practices offered Institutional repository or Data center No recommended practices offered [large data sets] IndividualNot appropriate Seattle, WA 20 May 2012CSE 2012 Annual Meeting 19

20 Recommended Practices: scope and general principles Definitions: sup. mat., article, data, metadata, etc. Curation and life cycle: selection, peer review, editing, presentation, providing context, referencing, citing, managing/hosting, discovery, preservation Intellectual property rights management Roles and responsibilities of authors, editors, reviewers, publishers, libraries, A&I services, repositories Business Working Group – policies Co-chairs: Linda Beebe (APA), Marie McVeigh (Thomson-Reuters ISI) Seattle, WA 20 May 2012CSE 2012 Annual Meeting 20

21 Metadata, incl. persistent identifiers Preservation, incl. archiving and migration Packaging for exchange and delivery Technical Working Group – “how” Co-chairs: Dave Martinsen (ACS), Sasha Schwarzman Seattle, WA 20 May 2012CSE 2012 Annual Meeting 21

22 Recommended business practices Integral sup. mat’sAdditional sup. mat’s Selecting / Peer reviewing At the same level as the article May not be reviewed at the same level CopyeditingAt the same level as article. Should be noted if not May not be edited at the same level. If so, should be noted Referencing within article Cite / link at the same level as table or fig. No ref. list entry: this content is part of the article Provide in-text citation and link at the appropriate point in text, rather than at the end IdentifyingDOI must be assignedDOI may be assigned References within sup. mat. Integrate references into the ref. list of the article (Biophysical Journal) Keep references separate from the article ref. list Seattle, WA 20 May 2012CSE 2012 Annual Meeting 22

23 Recommended business practices (cont’d) Integral sup. mat’sAdditional sup. mat’s PreservingPreserve at the same level as the article Provide the same level of metadata markup Include in migration plans Take preservation into consideration when accepting If uncertain about preservation, have author submit to a trusted repository and link to it Intellectual property rights Treat rights in the same manner as the rights for the article Anyone who has access to the article should also have access to Integral sup. mat’s Determination of rights for Additional content may differ and should be transparent to users Seattle, WA 20 May 2012CSE 2012 Annual Meeting 23

24 Recommended business practices (cont’d) Identifying / linking and managing sup. mat.  Sup. mat’s should be linked, bi-directionally, to and from the article  Integral and Additional content should not be mixed  If journal content is hosted by a host / aggregator it should also deliver supplemental materials  An author’s website is not an appropriate place for the sole posting of supplemental materials Seattle, WA 20 May 2012CSE 2012 Annual Meeting 24

25 Recommended business practices (cont’d) Discovering supplemental materials  Consistent placement, naming, and navigation - on the ToC - on the landing page - in the article - in the supplemental materials  Consistency across the articles and across journals  Aid A&I services by including metadata that indicate the function and format of the sup. mat’s Seattle, WA 20 May 2012CSE 2012 Annual Meeting 25

26 Recommended business practices (cont’d) Providing context for sup. materials Include on a landing page or within the content:  Article citation and DOI  Title and/or succinct statement about sup. mat’s  For multimedia: player, file extension, and size  List multiple files  Browser information, if supplemental mat.’ rendition is browser-dependent  Sup. mat. DOI or another persistent identifier Seattle, WA 20 May 2012CSE 2012 Annual Meeting 26

27 Recommended technical practices Minimal metadata  Article DOI  Supplemental materials DOIs  Supplemental materials function: Integral, Additional, or both  Supplemental material content description  File formats of supplemental physical objects Seattle, WA 20 May 2012CSE 2012 Annual Meeting 27

28 Recommended technical practices (cont’d)  Non-DOI IDs  Contributors  Titles  Languages  Creation date  Original or converted  Subject descriptors  Alt. descriptions (accessibility)  Summary for download  Content descriptor  Copyright and licensing  Preservation level  Application and platform - created with - to be used for rendering  Additional file information - file names, file sizes - mimetype, fixity, validity Seattle, WA 20 May 2012CSE 2012 Annual Meeting 28 Extended metadata for supplemental materials

29 Recommended technical practices (cont’d) Preservation  Publisher must choose its preservation strategy. WG recommends migration over emulation  Retention - Integral objects: original + two latest converted - Additional objects: original + the latest converted  File formats - Publishers uses formal registries, e.g., PRONOM, UDFR - Publisher defines the formats it will support Seattle, WA 20 May 2012CSE 2012 Annual Meeting 29

30 Recommended technical practices (cont’d) Packaging  Article and all its components should be transferable in a single package, e.g., to fulfill interlibrary loan request, to perform a deposit to an archive or a repository, etc.  There are a number of different packaging specifications available, and this Working Group does not intend to design a new one nor require the use of any particular specifications or tools. Seattle, WA 20 May 2012CSE 2012 Annual Meeting 30

31 Recommended technical practices (cont’d) Manifest - Journal ID (ISSN) - Article ID (DOI, citation) - Supplemental materials DOIs - List of all files contained in the package. For each:  Function: Integral, Additional, or both  File name, File size, File description  Rendering application information  Detailed copyright information  Instructions Seattle, WA 20 May 2012CSE 2012 Annual Meeting 31
