What is in the Pandora’s box?

• Multimedia: video, audio, virtual reality• Chemical, crystallographic, and protein structures,

gene sequences, 3-D images• Computer programs (algorithms, code, libraries,

and executables)• Tables, Figures, Text (Experimental procedures,

Extended methodology, Survey results, Derivations, Extended bibliographies, …)

• Data sets (data sets are not the focus of this group)

Page 11: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

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.

Page 12: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Questions to ponder

• Degree of importance. Are all components of supplemental materials equally important? As a busy 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?

Page 13: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Questions to ponder (cont’d)

• 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 conversion. 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?

Page 14: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Questions to ponder (cont’d)

• 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 identification, description, linking, preservation, and other processing of sup. mat., what sustainable business models could support the expense?

Page 15: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Who cares? You should – if you are an …• Author / Editor• Reviewer• Reader• Publisher• Hosting platform / Institutional Repository /

Data center / Individual• A&I service• Reference linking and Citation indexing service• Librarian / Archivist / Historian of scholarship

Page 16: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

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!

Page 17: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

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"

• 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 – policiesCo-chairs: Linda Beebe (APA), Marie McVeigh (Thomson-Reuters ISI)

Page 21: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

• Identifiers for supplemental materials• Linking to and from supplemental materials• Archiving, preservation, and forward migration

of supplemental materials• Packaging, exchange, and delivery of

supplemental materials• Metadata and granularity of markup

Technical Working Group – “how”Co-chairs: Dave Martinsen (ACS), Sasha Schwarzman (AGU)

Page 22: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Supplemental materials: Pseudo vs. truly

• Print model: article layout implicitly reflected functional distinction between essential and nonessential elements (body vs. appendix)

• Mixed electronic-print model: both essential and nonessential components are often treated as “supplemental materials”

• Is the material essential or not? This must be stated explicitly for machine and human reader

Page 23: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Pseudo-supplemental (example)

Page 24: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Classification facet 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

Page 25: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Classification facet 2: Custody

• PublisherRecommended practices offered

• Institutional repository or Data centerThe publisher has no responsibility or authority over content and does not host it. No recommended practices offered

• IndividualNot appropriate for hosting supplemental materials

Page 26: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Supplemental materials classifications: Integral, Additional, Related

Page 27: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Recommended business practicesIntegral content Additional content

Selecting / Peer reviewing

At the same level as core article

May not be reviewed at the same level

Copyediting At the same level as core 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 article

Provide in-text citation and link at the appropriate point in text, rather than at the end

Identifying DOI must be assigned DOI may be assigned

References within sup. mat.

Integrate references into the ref. list of the core article(Biophysical Journal)

Keep references separate from the core article ref. list

Page 28: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Recommended business practices (cont’d)Integral content Additional content

Preserving Preserve at the same level as the core 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 core article

Anyone who has access to online article should also have access to Integral content

Determination of rights for Additional content may differ and should be transparent to users

Page 29: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Recommended business practices (cont’d)

• Identifying / linking and managing sup. mat. Sup. mats. should be linked, bi-directionally, to and

from core 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

Page 30: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Recommended business practices (cont’d)

• Discovering supplemental materials Consistent placement, naming, and navigation Indicate sup. mat. presence on ToC, landing page Link to Integral content from within the article Link to Additional content on the first PDF or HTML

page of the article Aid A&I services by including metadata that indicate

the purpose and format of the sup. mat.

Page 31: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Recommended business practices (cont’d)

• Providing context for sup. materialsInclude on a landing page or within the content: Core article citation and DOI Title and/or succinct statement about the content For multimedia: player, file extension, and size List multiple files Browser information, if supplemental content

rendition is browser-dependent Sup. mat. DOI or another identifier, if assigned

Page 32: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Technical considerations

• Heterogeneity: an archive (ZIP, TAR, RAR), a document (PDF, MS Word), or a virtual collection (web page) may contain both Integral and Additional content. The two may need to be treated differently in terms of identification, linking, preservation, and metadata assignment

Page 33: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Page 35: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Technical considerations (cont’d)

• Hierarchy and Recurrence: an archive may contain a tree with many branches and sub-branches with nested objects and groups

• Granularity down: what to identify — entire sup. mat., groups, objects, …? At what level do you stop?

• Granularity up: link to a specific item within the core article or to the core article as a whole?

Figure S6. Coordinated Annotation of the Individual Chromosomes for Beijing indica and Syngenta japonica

We depict all the genetic markers, nr-KOME cDNAs, FGENESH gene predictions, and transposable elements identified by RepeatMasker. Genes are depicted as WH (colored blue) or NH (colored red) based on their similarity to Arabidopsis. TEs are decomposed into classes I, II, and III. Correspondence between indica and japonica is indicated by drawing a connecting line between the 5 ends of the nr-KOME cDNAs ′that clearly align to both assemblies.

Page 38: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Technical considerations (cont’d)

Supplemental objects types:• Individual (atomic) items• Physical containers (e.g., ZIP, PDF) with:

unrelated objects logically different objects that share some common

metadata, e.g., a series of graphs or images• Logical wrappers

Page 39: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Technical considerations (cont’d)

• Logical wrapper: a shell around multiple physical representations of the same logical object, e.g.,A chemical structure represented by: a connection table, an image of a molecule in a static orientation, and an interactive application allowing manipulation by the viewer.Protein-related information represented by: analytical measurements, chemical structure, and derived structures.

Page 40: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Identification

1. All Integral Supplemental content MUST be assigned its own identifierRationale: Any content item that is critical to the

understanding of the article but which is located and maintained separately from the article body should be uniquely identified to enhance linking reliability (e.g., hosting of the content item may diverge from that of the article body).

Page 41: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Identification (cont’d)

2. All supplemental content items that are applicable to more than one article SHOULD be assigned an external identifierRationale: Linking to the content item may need to

occur from various publisher platforms.Examples: http://dx.doi.org/10.1109/TUFFC.2009.1248/mm9 http://dx.doi.org/10.1787/oif-2008-table2-en

Page 42: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Identification (cont’d)

3. Supplemental content items that are an aggregate of (potentially many) individual elements or records SHOULD be assigned an external identifier.Rationale: The content has its own intrinsic value outside

the context of the article and should be discoverable on its own.

Examples: http://dx.doi.org/10.5061/dryad.125http://dx.doi.org/10.1371/journal.pbio.0030038.st004

Page 43: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Identification (cont’d)

4. Supplemental content items that are uniquely described by sufficient metadata MAY be assigned an external identifier. Rationale: The content has its own intrinsic value outside

the context of the article and may be discoverable on its own. Any effort expended in assigning descriptive metadata can best be exploited via an external identifier.

Examples:http://dx.doi.org/10.1371/journal.pbio.0030038.g002 http://dx.doi.org/10.1371/journal.pbio.0030038.t003

Page 44: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Identification (cont’d)

5. Supplemental content packages (e.g., a container holding several supplemental items) MAY be assigned external identifiers. Rationale: Enhance linking reliability.Examples: http://dx.doi.org/10.1037/0097-7403.32.3.322.supp http://dx.doi.org/10.1037/0735-7044.122.4.777.supp http://dx.doi.org/10.1371/journal.pbio.0030038.sg008http://dx.doi.org/10.1172/JCI200521773DS4 http://dx.doi.org/10.2210/pdb2fpe/pdb http://dx.doi.org/10.1787/548525556001

Page 45: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Preservation

1. Publishers should state publicly their preservation strategy/approaches. Out of the two main approaches (migration vs. emulation) migration is recommended as the preservation strategy. Migration involves converting objects, over the long-term, from one form to another which is usable under prevalent technology at the time.

Page 46: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Preservation (cont’d)

2. Retention of files – Ideally, all objects throughout the migration chain should be saved. For the Integral Content, at least the original object

plus the last two iterations of the converted objects, i.e., latest and latest-1 versions, must be saved.

For Additional Content, publishers should strive to save the original object plus the converted objects.

Page 47: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Preservation (cont’d)

3. Format is important – preservation techniques depend on object format. Format is not equal to mime-types, which may not carry enough information for converting and management of objects. If possible, publishers should use formats defined in formal format registries like UDFR http://www.udfr.org or PRONOM

http://www.nationalarchives.gov.uk/PRONOM/

Page 48: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Preservation (cont’d)

Alternatively, publishers may define and publish list of file formats they support. Criteria: Is the format open or proprietary? Is the format widely used? Is there already a standard format for this type of content? Does this format have advantages over existing formats for this type of

content? Are there free/ubiquitous viewers? Are there viewers for multiple operating systems? Are there any concerns about long term viability? Is there open source software related to the format? Is the format defined/reviewed by an international standard (both

formal or de facto) or a widely recognized body?

Page 49: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Preservation (cont’d)

Limitation of formats accepted by publishers – While it is an acceptable practice to limit the formats of objects to be supported, authors should be able to deposit objects in formats outside of the acceptable list. Conversion to archival format - publisher lists required/preferred

formats for preservation/carried forward. Objects outside of the list should be converted to a supported format. Both the original and converted objects will be kept.

Two-tier service - publisher lists formats to support. Other formats will still be accepted but not guaranteed to be carried forward. Each object should have basic descriptive metadata, like label and caption, to inform users what the object is about, in case the format becomes obsolete.

Page 50: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

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.

Page 51: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Packaging (cont’d)The package contains all files comprising the

article and the manifest describing the contentsManifest – article-level metadata:

1. Journal ID (ISSN)2. Core article ID (citation)3. Core article DOI4. Persistent links to the supplemental materials5. List of all files contained in the package

Page 57: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Version of record

• If the version of record incorporates linked or embedded essential objects then the notion of Integral Supplemental material is not applicable

• Additional content still has to be indicated as such, e.g., AGU’s “Auxiliary material”

• Is version of record the same for various actors?

Page 58: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Version of record (cont’d)

Page 59: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

Practical challenges

• Is sup. mat. importance “in the eye of the beholder?” (what’s Additional to you is Integral to me) — some beholders are more equal than others: a decision made upfront determines downstream processing

• Real costs, hypothetical benefits• Business models: is sup. mat. a money maker

or a money waster?

Page 60: NISO-NFAIS Supplemental Journal Article Materials Working Group: An Update on an Industry Initiative

What does the future hold?

“… over time the concept of supplemental material will gradually give way to a more modern concept of a hierarchical or layered presentation in which a reader can define which level of detail best fits their interests and needs.”Marcus, E.
