ORCID: Open Researcher Contributor Identification Initiative - Home - http://science.thomsonreuters.com/orcid...
Name ambiguity and attribution are persistent, critical problems imbedded in the scholarly research ecosystem. The ORCID Initiative represents a community effort to establish an open, independent registry that is adopted and embraced as the industry’s de facto standard. Our mission is to resolve the systemic name ambiguity, by means of assigning unique identifiers linkable to an individual's research output, to enhance the scientific discovery process and improve the efficiency of funding and collaboration.

Fantastic article! Finally: "But perhaps the largest challenge will be cultural. Whether ORCID or some other author ID system becomes the accepted standard, the new metrics made possible will need to be taken seriously by everyone involved in the academic-reward system — funding agencies, university administrations, and promotion and tenure committees. Every role in science should be recognized and rewarded, not just those that produce high-profile publications."

- Karen James
Second time in a week that someone stated "publishers don't care about format of submissions". Again I ask: if that's the case, why do all journals make a huge deal about it in their instructions to authors?
- Neil Saunders
As for universal format: easily solved by writing our papers on the web. Imagine a simple forms-based interface with fields for title, authors, abstract, introduction... Imagine a button in Google Docs that says "submit this document to <insert journal here>" !! But currently, we all like to use our own word-processing software on our own machines, then upload a document in a multitude of formats. It's going to take a big shift in thinking and work practices.
- Neil Saunders
What Neil said: if journals don't care, why do they make such a damn song and dance about it? Why not explicitly say you can *submit* in any basic AIMRAD format? Worry about format after acceptance: either the journal can send it to India per Ian above, or if they make the authors do it at least they only have to do it once. My next paper (quit laughing) is going out in basic AIMRAD...

Neil & Bill: maybe "don't care" is to strong a phrase.

the publishers i know would be delighted to standardise to NLM DTD for submissions -- would save lots of editorial time and production costs -- the publisher i know best sends accepted papers to be manually turned into xml which can then be used for PMC deposition and the semi-automatic generation of the HTML and PDF versions. But things like the Publicon app have taught publishers that implementing the technology to do something doesn't mean that it will happen in significant quantities! :)

- Martin Fenner
There is a nascent version of that working in neuroscience http://nprc.incf.org/. Journals have formed a consortium where if an author submits to one journal and it gets rejected, the author can specify that the reviews follow the paper to another journal so that it doesn't need to be re-reviewed. This was viewed as a way for papers that have nothing wrong with them but which don't fit the scope of the journal can be published more quickly and easily.

- Mr. Gunn
Aside from making life easier for authors, it would allow sane computational use of papers. With PDF, you don't even know which image a figure legend refers to, except by guess work. The difficulty is that the journals don't see it as their problem. The solution is for the authors to make it the journals problem

Neil, great post. And you're right, we do make things too complicated sometimes, but do we do that at the level at which we ask questions, or at the software implementation level? My take is the latter, cause you need to ask questions the way you want to, but that doesn't mean what makes it all come together has to be one complex mess

Glad you like it. One of those that bubbled up out of frustration at inability to achieve! I feel that science is the business of turning complex (real-world) things into simple models - and that we've moved away from that idea.
- Neil Saunders
I'm a sucker for this kind of ambitious thinking. Go Neil!
- Bill Hooker
I think it's a good sign that things like this are now obvious. Things start out as a complex mess of disconnected things, overlapping complicated ways of connecting them are devised, then it becomes obvious what the simpler thing to do is.
- Mr. Gunn
Great ! But aren't you re-inventing something like RDF Neil ? feature/probe/value is nothing but a RDF statement...
- Pierre Lindenbaum
No, I don't want to reinvent anything. If RDF will work for me, I'll use it. I'll also use SQL, NoSQL, key-value pairs, document-oriented or whatever it takes. I just think that trying to integrate data by combining other peoples large, complex representations is not working. We need to simplify the whole business.
- Neil Saunders
I think there is a middle road here - we need high level generic descriptions like what Neil is proposing (and like my "We have stuff, we do stuff to it, which makes stuff"), but also a way of pointing to more sophisticated information that might be useful in specific contexts. I think we can have the best of both worlds as long as the data representation is separated from the metadata and the organization of each can be described in a machine readable (and agreed!) form
- Cameron Neylon
I'm too old school, leaving comments on blogs... who does that any more. I’m sure you’re aware that you’ve just described a model using *triples*. Which means you could start storing these kinds of simple relationships in a triple store like virtuoso etc. As you say, you don't have to reinvent anything, just simplify the use (conventions) of existing approaches (e.g. RDF). I would like...

@Greg about the web interface, one cool interface for adding RDF statements/triples is freebase/Acre: http://www.freebase.com/apps/
- Pierre Lindenbaum
I like blog comments :-) Yes, my example looks like RDF triples. No, that was not really my intention. Let's ask these questions: (1) what data relationships would make sense to a biologist? (2) what are the commonalities in the data, which a biologist may not have considered at an abstract level? As I wrote in the post, many datasets that look different are really different ways of looking at the same thing.
- Neil Saunders
The joys of data modelling :-) For (1): I'm afraid asking for a definition of some data relationships is building an(other?)) ontology.
- Pierre Lindenbaum
Let's put it another way. What we have, presently, are quite complete, often large and complex, but useful and usable descriptions of individual experiment types. "Integration" essentially means "parse them individually and mash-up the results". That's what makes it difficult. Perhaps we need an "ontology of integration" :-) But let's keep it really, really minimal.
- Neil Saunders
I actually think you will struggle to find data commonalities across bioscience. Even the simple proposal of target, measurement, value could break down in many cases e.g. we tried ages ago to get some intensity data from a bunch of microarray experiments and we gave up because we couldn't get across what we needed. What are you really measuring? Does it mean the same thing to different...
more...
- Cameron Neylon
I think there's a good case for storing, in the first instance, raw values. Figure out how to process them later (that's statistics). Focus on trends (up, down, stayed the same). Focus on well-defined variables that do mean the same to everyone (intensity, in theory = amount of transcript, regardless of the very real difficulties). And I think more experiments fall into...

@Pierre freebase is exactly what I had in mind, however the web client (the best part) is not open. @Neil Store the data first, ask questions later. Nice.

But you start down that path, and you suddenly realise that the semweb is asking you to get your data...

But for me your example of a gel isn't raw data. The raw data is the image. Which might have several targets or assays on it.

And in microarrays, "raw" data is the image of the slide. But aside from a cursory inspection to ensure that it isn't complete rubbish, nobody much cares about that. I'd argue that there's a point in the preprocessing at which a numerical value emerges which could be called "useful" and which encapsulates the object being measured. It needs more work (e.g. normalization) to get information from it, but it's the "value" in feature/reporter/value.
- Neil Saunders
To me this about finding something a bit like an upper ontology that describes the general category that objects (targets, assay, value, inputs, outputs, data, process, sample) fall into. That lets you do the general integration, and the more detailed local data structures become more useful as you can agree more and more on what details are important. So I absolutely agree with what...

- Neil Saunders
Dorothea, sure, not a problem.
- Neil Saunders
"This is a gel", "this is a sample",.... AFAIK all those kinds of statements are part of the OBI ontology: http://obi-ontology.org/page... e.g. "Agarose Gel" http://bioportal.bioontology.org/ajax_co...

Sure, and those are very complete descriptions of experimental components. But what I want is: "I saw A on my gel, B in my LC/MS, C on my expression array and D on my SNP array and when I plug all that into some Bayesian predictor, it says cancer" :-)

Ontologies are not the issue, it's more low level than that. I also work with microarrays, proteomics, metabolomics, and numerous physiological data sets.

My argument would be that the reason you're less productive is not because of the RDF and ontologies per se, but because the ontologies aren't really built for what we want to do.

- Lars Juhl Jensen
Tab-delimitted files would be grrrreat for me in my lab. If any of the rest of you would like to share our data, however, then you're completely screwed. Is the problem not that we're all duplicating each other's work by writing the same kind of parsers for the same kind of data? Proteomics (for example) has a standard (http://www.ebi.ac.uk/pride/). Is it really so hard to use / develop the community-based tools that are being generated around this standard?!?
- Neil Swainston
Well, the ratio of usable tools to schemas/ontologies is a whole other debate :-) But sure, in principle the tools are there - for individual types of data. What I highlight in the post is the difficulty of genuine data integration, as opposed to the current "write a parser for everything and mash it up" approach.

Chris M makes an important point wrt data levels, analogous to trace archives vs sequence dbs. Extending the sequence analogy, obsoleting levels will become important (it will rapidly become cheaper to resequence rather than store sequence).
