It was envisaged in the Project Proposal Template that each proposal would have a number.

"HIP identifier a short description plus a serial number with a version (for example this document is Template for a Hyperledger Improvement Project HIP 0.2)"

The proposals that have been incubated have not been assigned numbers so far.
The assignment of HIP numbers and the assembly of the links to the various proposals from one page will assist the discovery of the various proposals under incubation or in other stages of adoption. As the number of projects under incubation as well as the breadth of our activities increase this would be very useful in increasing our transparency.

I suggest that we assign numbers to the already existing proposals

and any other proposals being incubated. These can be linked to from a top level page in the wiki.

In some of the open source projects like Bitcoin an editor is responsible for assigning the numbers. For a sample page from bitcoin please look at  https://github.com/bitcoin/bips.

Comments and questions are welcome,
