In general “research data” refers to raw or processed products of a research project. These products can be video, images, or numeric files in the form of geographic information, spreadsheets, and other formats.

Editor's Notes
- Hi! I’m Michelle Hudson. I’m the science and social science librarian working in the social science library for now, but I’ll be in the new Center for Science and Social Science Information when we open in January up in the Kline Biology Tower.I started at Yale in April and I’ve been going to conferences and workshops all summer – today I’m going to talk about things I learned at the Summer Institute on Data Curation put on by UIUC’s GSLIS and the NSF-funded Princeton Research Data Lifecycle Workshop.
- Director of CIRSS -- Center for Informatics Research in Science & Scholarship
- As well as many other things – too many to list.
- No standards for storage or metadata either within or across disciplines in many cases.
- Poor interoperability makes it difficult to maintain or convert data to appropriate formats – open source software and standards are lacking.
- Even simple ones to standardize the outcomes of experiments – people don’t talk about things the same way.
- Some data are cheaper to generate than to store. That’s not to say they’re cheap to generate – it’s just that adequate backed-up storage is still unreasonably expensive for most research enterprises.
- Domain of stewardship/responsibility - whose job is it to keep university assets for thirty, forty years or more? liaison models and services to researchers. Who can give this authority and who is willing to fill the gap? As a discipline, we don’t have liaison models in place. Is it the library? Is it IT?
- So Cornell has a repository with a lot of great data they’re willing to share. This isn’t helpful unless we know data sets are stored there. It’s even less helpful if we can’t access them. This is true for all kinds of universities and centers all over the world.
- Utilizing software that tracks and records the progress of experiments and keeps data as it happens is something that’s gaining more popularity. Every scientist uses a notebook, and, until recently, these notebooks were paper and shelved somewhere inaccessible or forgotten once the project was done. With electronic notebooks, it’ll be easier to keep track of what’s done to the data, when, etc.
- Automatic metadata application came up as a main point during the Princeton workshop. Scientists want to advocate for instrument makers to give more robust options for creating metadata at the point of data creation/observation.
- If we start early in the workflow, it’s easier to get usable data we can decide to select and keep with less work down the line. If data is taken care of early with the aim of keeping it safe for a long time, it would require less work on the part of the curators.
- Some institutions are beginning to educate grad students on good data management techniques. Simple data or file management isn’t often taught as part of a research methods scope, so students have been welcoming this information, and see librarians as experts on this kind of thing.
- DataONE and the Data Conservancy are two NSF-funded projects with important goals for nation-wide cyberinfrastructure and research data storage. DataONE intends to connect “nodes” of research institutions to make the data they share widely available. They also have a mission to educate students, librarians, and researchers on data management best practices. The Data Conservancy is a model for a large-scale repository for research data. Instances will start rolling out as early as next year and it’ll be interesting to see how it develops and if it’s viable. You can read a lot more about it on their website, which is on your handout.
- Feel free to talk to me about anything else related to data as well. Obviously not much time to cover it all today, but let’s meet and chat! Also refer to the handout for good resources on learning more.
