1 Overlay Journal Infrastructure for Meteorological Science (OJIMS) Sam Pepler RIOJA, Monday July 7th, 2008 University of Cambridge, UK

2 Outline The OJIMS project, Aims and Who’s involved Data Journal MetRep – A subject based repository for Meteorological science. Proposed overlay mechanisms

3 Outline The OJIMS project, Aims and Who’s involved Data Journal MetRep – A subject based repository for Meteorological science. Proposed overlay mechanisms

4 The OJIMS project Overlay Journal Infrastructure for Meteorological Science JISC and NERC funded. The project has three main aims:  Creation of overlay journal mechanics.  Construction and evaluate business models for potential overlay journals.  Creation of an open access subject based repository for Meteorology and atmospheric sciences.

5 Who’s involved The University of Leeds, who will development a dataset review policy with RMetS on behalf of the NCAS universities. Leeds is the NCAS lead university. The British Atmospheric Data Centre, who will setup and maintain a document repository. BADC is part of NCAS. The Royal Meteorological Society who will examine sustainable delivery models

6 Outline The OJIMS project, Aims and Who’s involved Data Journal MetRep – A subject based repository for Meteorological science. Proposed overlay mechanisms

7 CLADDIER: Published means available and some form of independent review.

8 What are the benefits of a data journal? Extend the value of peer-review from papers to data, to provide assurance that data documentation meets the necessary scientific standards.  Metadata standards  Independently understandable  Re-useable Provide an overview of the quality and applications of data, enabling it to be used more easily and appropriately in research and applications.  Adding independent quality statements about usefulness. Provide recognition for the work of collecting and describing data.  High quality, reusable data is not presently a citable resource  The writers of papers are not necessarily the data creators Raise awareness of the meteorological datasets available to UK and international community.  Discovery of data via citation

9 Why make an overlay journal? Because the data are already in a repository – The data is already available, it just needs some independent review. Because data is bulky, compound and complex – not easy to copy.

10 Outline The OJIMS project, Aims and Who’s involved Data Journal MetRep – A subject based repository for Meteorological science. Proposed overlay mechanisms

11 MetRep Filling a gap in the market. There is no store for some of the items we would like in the data journal. Gray document repository What's the selection policy:  Most types for item  Items must be relevant to Meteorological Science  Any author (not an institutional repository)

12 Examples of MetRep items  A paper from Weather  A set of pictures illustrating cloud forms  A report documenting a file format for climate models  Weather balloon data  A recording of a interview with ministers about climate change  The IPCC reports  The logo for a research programme

13 Could we use existing repositories?  A paper from Weather – NORA, IR?  A set of pictures illustrating cloud forms – JORUM  A report documenting a file format for climate models – BADC, RoRRI?  Weather balloon data – BADC  A recording of a interview with ministers about climate change – RMetS website  The IPCC reports – Website, IR?  The logo for a research programme – programme website.

14 Existing repositories – Could we use them? Institutional repositories  NORA  university IR Object type repositories  Arxiv  NORA  BADC Subject repositories  Arxiv  BADC

15 MetRep as an overlay repository Shouldn't data be in the BADC and MetRep? Shouldn’t a paper be in NORA and MetRep? What we mean by being in the repository is that the item has been submitted, been found to be in scope and will be stored. If we separate the submission and content review from the storage function then we have an overlay repository.

16 Outline The OJIMS project, Aims and Who’s involved Data Journal MetRep – A subject based repository for Meteorological science. Proposed overlay mechanisms

17 Overlay documents Document, dataset or other item. Reference- able via a resolvable id in a trusted repository. Overlay document Metadata about the overlay document Reference to document Discovery metadata for the referenced document Review process information

18 Version of document in review cycle  Submitted by author  Sent for review  Published Public comments Description of review process Digital signatures?

19 Metadata about the overlay document Author (of overlay not the referenced document) Other Dublin core fields

20 Discovery metadata for the referenced document and Reference to document Dublin Core metadata harvested from document Resolvable reference to document Other identifiers for document

21 Data repositoryDocument repository Repository Overlay repository Overlay document

22 Advantages of this approach Its clear that this is a document about another document. The two items are distinct self contained. Authorship for the referenced and referencing document are allowed to be different. Others can submit a document for review. The Overlay document has the same meaning as a stand alone item. You can take the out of the its repository context and its still meaningful. Review mechanisms and repositories do not need adapting to deal with these items. You can review a private document/data set. Answers the “is thing worth buying?” question.

23 Disadvantages of this approach Authentication issues. What if the author does not wish for document to be reviewed

24 Implementation Atom XML representation Already a popular format with many tools. Need a tool to create the records Need a web rendering method

Overlay document Metadata about the overlay document Reference to document Discovery metadata for the referenced document Review process information

26 Trusting repositories More than resolvable identifiers. Need to believe the object is preserved. Need to know preservation means for complex objects. Repositories need to have sound footing (but there are not absolute guarantees).

27 Summary The OJIMS project is about widening review processes beyond papers. This means storing a wider range of objects – MetRep. Data is a good example of valued stuff which is not recognised in a formal manner – Hence, the data journal. Because lots of repositories are already storing the things we think are valuable, we are going to implement MetRep as an overlay repository. To reuse existing tools for repositories and journals we are going to use overlay documents. These will be based on atom documents. Need to trust repositories to make any overlay work.
