PhenoData is designed to store the data from HEP papers that are not provided on arXiv or HEPData and to avoid the duplication of work by HEP researchers in digitizing plots. The data is in the form of digitized curves from figures, tables, etc. and can be easily searched by paper title, paper IDs (via arXiv, DOI or preprint numbers) and uploader name. Registration is not required to view existing data but to upload your own data you must register at HEPMDB.

PhenoData is in development stage. Please contact us with your questions/suggestions here or via the Launchpad.

Uploading Data

To upload the data from a certain paper you will need a URL link to the paper's arXiv or other identifier reference page, the data file in any textual format and a pdf or image file of the figure in question. Multiple data can be added to a certain paper by clicking the New Data option.


The PhenoData API allows you to upload a lot of data while avoiding the interactive upload via Web Interface. It can be used to access endpoints, which allows you to upload data and view papers stored in the database.

The base API endpoint is the URL: "".

Registered users are provided a unique API key which should be included in all API requests to the server. An example of the bash script for the upload of the data is available here, including an example of the data file.
