Skim stands for 'Simple knowledgebase for insightful metabolomics'. Skim is a is a free, open-source framework for simplifying interpretation of high throughput metabolomics data. There is a considerable gap between our ability to produce metabolomics data and our ability to analyze it to gain systems-level insight into the biological processes that produced the data. By pooling our collective insights into metabolomics and by developing novel tools to query, aggregate and analyze this collective pool of knowledge, we can address the sore lack of tools for producing biologically relevant knowledge based on quantitative information.
Skim is currently under testing. Feel free to play around, but features, layouts and other things may be altered considerably. Feel free to leave a notebook post with the tag "feature request" to suggest new features!
Skim relies on two sources of metabolite, reaction and pathway information: Highly curated databases such as the KEGG PATHWAY Database and valuable insights and inputs provided by users such as yourself.
In addition to serving as a repository for your thoughts, opinions and conjectures, we are also developing tools by which you could query yours (and others') inputs. We envision these tools will go well beyond simple word-based searches. They will incorporate advanced natural language parsers to determine the structure of user inputs and provide a rapid overview of the knowledge base. The Skim framework will eventually provide an API that would allow you to develop your own methods for querying and analyzing the information in Skim.
Skim does not use a traditional (relational) database. It is built on top of CouchDB, a document-based database. This database provides unparalleled scalability and flexibility in the development of Skim. The kinds of tools and data sources relevant to metabolomics are continuously evolving. We do not know how your data analysis and storage needs evolve. CouchDB was built with exactly such a scenario in mind.
Every piece of information entered or queried as part of the Skim framework, (including this HTML page) is stored as a document. It is accessible over pure HTTP in a RESTful manner. These documents can be schema-free, and range from fully structured (quantitative data tables) to fully unstructured (quick notes in your notebook).
Because of the REST interface and the document-based model, replication of the database (and all its applications) is trivial. You can install your own CouchDB server and replicate this entire website locally if you wish.
