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.

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

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

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
![Page 9: Overlay Journal Infrastructure for Meteorological Science (OJIMS) Sam Pepler RIOJA, Monday July 7th, 2008 University of Cambridge, UK](https://reader035.vdocuments.net/reader035/viewer/2022062620/551afe52550346f70d8b5486/html5/thumbnails/9.jpg)
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.

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 repositoryWhat's the selection policy:
Most types for item Items must be relevant to Meteorological
Science Any author (not an institutional repository)
![Page 12: Overlay Journal Infrastructure for Meteorological Science (OJIMS) Sam Pepler RIOJA, Monday July 7th, 2008 University of Cambridge, UK](https://reader035.vdocuments.net/reader035/viewer/2022062620/551afe52550346f70d8b5486/html5/thumbnails/12.jpg)
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
![Page 13: Overlay Journal Infrastructure for Meteorological Science (OJIMS) Sam Pepler RIOJA, Monday July 7th, 2008 University of Cambridge, UK](https://reader035.vdocuments.net/reader035/viewer/2022062620/551afe52550346f70d8b5486/html5/thumbnails/13.jpg)
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.

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

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.

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.

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

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).
![Page 27: Overlay Journal Infrastructure for Meteorological Science (OJIMS) Sam Pepler RIOJA, Monday July 7th, 2008 University of Cambridge, UK](https://reader035.vdocuments.net/reader035/viewer/2022062620/551afe52550346f70d8b5486/html5/thumbnails/27.jpg)
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.
