Data is a Springer Nature journal focused on data publication. The main article
type is a Data Descriptor, which depicts rigorously described, reusable
datasets. Each Data Descriptor is accompanied by metadata represented in
the ISA-Tab format, which is a tabular format following the
The ISA-explorer tool  uses the information in the Scientific Data
ISA-Tab metadata files to facilitate dataset discovery. The tool allows
users to filter datasets by different criteria: for example, a specific
design type or data stored at a particular repository.. The filters can
be combined in a boolean search allowing users to easily and quickly
discover specific types of data.
The ISA-explorer also offers a generic search box, allowing for
keyword-based searches of the ISA-Tab metadata files. Additionally, the
tool allows browsing of dataset specific information such as related
publications and a visualisation of the distribution of the
characteristics of the samples involved in the study generating the
We have some improvements already planned; for example, showing overall
statistics, supporting richer query searches considering the semantics
of the data (e.g. query expansion based on synonyms) and relying on
richer knowledge representations (such as linkedISA ).
