Not only the reporting of ('positive and negative') raw data, but more comprehensive metadata are needed to advance this area.
The experience of the OTN project is that this is important and that an easy to implement and user friendly software solution is needed to provide metadata of all the data in a consistent way through a single interface.
The study shows that systematic investigation of user-generated collection-level metadata in Flickr and other similar open-tagging sites is needed to help inform better design of collection metadata schemas and other information organization tools.
But that is not the case at the moment, so a further layer of software is needed to infer the metadata from web pages, e-mails and other electronic documents.
Further work is needed to establish the reproducibility of metadata annotation.
More research is needed to compare different ways of generating meaningful features from both metadata and lyrics.
Thus, biocuration of RNA-Seq metadata is needed.
Biological "metadata standards" will be needed to describe all data from all sources in the same format.
To understand data, better metadata are needed.
Well-structured data and consistent representation of metadata are needed for accurate data integration and cross-study analyses.
