FTP site layout for the cHPP

This document is a request for comment on a proposed FTP site layout for the chromosome-based Human Proteome Project, cHPP. The RFC process began on February 23, 2011 and will end on March 24, 2012.

There have been a number of efforts to construct novel repositories for proteomics data and documents over the course of the last decade. This RFA does not seek to duplicate those efforts. Instead, it is a proposal for how to construct standard, navigable FTP sites that can be used for short- and long-term information storage and exchange by participants in the cHPP and other interested parties.

Demonstration site

For the purposes of demonstrating by example, an FTP site has been established at ftp.proteomecentral.org using the principles described in this document. This site will be modified to stay in compliance with this RFA as changes are suggested.

Required folders

The base folder for any particular project will be:

chrNn

where Nn is the number of the human chromosome associated with the project, padded with a leading zero so that Nn is two characters long. For example, for chromosome 1 (chr01) and chromosome 20 (chr20). For chromosomes with no number, the following special names will apply:

1. chrX - X chromosome;
2. chrY - Y chromosome; and
3. chrOther - all information that cannot be readily assigned to a chromosome.
