ACCESS THE DATA

Table of contents


We have datasets from a total of seven assays, each accompanied by its corresponding metadata. All experimental data and metadata are stored and managed in a relational database management system (RDBMS). The Understand the data page explains the database schema.

Data composition and table-wise data download

If you plan to explore datasets through a browser, we recommend accessing the data for each table via the CMI-PB API or using the uniform resource identifier (URI) format, such as https://www.cmi-pb.org/api/<table_name> to download data for each table. Below are the table-specific data URIs.

Application programming interface

CMI-PB API works with simple, human-readable URIs ('REST' = Representational State Transfer'). These can be used to resolve and to map identifiers in CMI-PB, and to directly fetch networks and other data items in a number of formats. For more details, please refer to the API documentation which you can find in the developer section of help pages.
