Dave,
I suspect the convergence is because they are all heading towards a simple RESTful HTTP GET service rather than by dint of their common ancestry.
If one were to start from scratch today having never seen z39.50 then one would probably come up with something similar.
All the best,
Roger

Hi Ryan, there is indeed a good deal of similarity between the interfaces exposed by TAPIR and SRU. I suspect there would be mostly superficial alterations required to the TAPIR key+value URL interface to support much of SRU.
As an aside I find it interesting, and somewhat encouraging that the both SRU and TAPIR derive from a common ancestor (z39.50) and though taking divergent development streams, seem to arriving at similar outcomes. Convergent evolution of protocols.

Hello TAPIRians,
I've recently moved from the library world into the biology world, and I'm noticing that TAPIR has a lot in common with the SRU standard that is gaining popularity in the library world. I would like to encourage collaboration between the two communities, and see whether it is possible to forge a single standard out of the two. One major difference is that TAPIR is database-oriented, while SRU is much more document-oriented, but this should be possible to overcome.
SRU has been recently been turned over to the OASIS standards body as source material for developing a general-purpose web services search standard. As a part of this standardization process, the initial draft document has been opened for public comments (see below). If you have comments, you can post them at the URL indicated. If you work for an institution that is a member of OASIS, I believe you can still join the committee and vote on issues related to the standardization.

To OASIS members, Public Announce Lists:
The OASIS Search Web Services TC has recently approved for public review the following Discussion Document:
Search Web Services v1.0 Discussion Document
This document: "Search Web Services Version 1.0 - Discussion Document - 2 November 2007", was prepared by the OASIS Search Web Services TC as a strawman proposal, for public review, intended to generate discussion and interest. It has no official status; it is not a Committee Draft. The specification is based on the SRU (Search Retrieve via URL) specification which can be found at http://www.loc.gov/standards/sru/. It is expected that this standard, when published, will deviate from SRU. How much it will deviate cannot be predicted at this time. The fact that the SRU spec is used as a starting point for development should not be cause for concern that this might be an effort to rubberstamp or fasttrack SRU. The committee hopes to preserve the useful features of SRU, eliminate those that are not considered useful, and add features that are not in SRU but are considered useful. The committee has decided to request OASIS to release this as a discussion document. Detailed review of this document is premature at this point and is not requested; feedback on the functionality and approach is solicited. Feedback is requested by December 7.
The public review starts today, 7 November 2007, and ends 7 December 2007. This is an open invitation to comment. We strongly encourage feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of OASIS work. Please feel free to distribute this announcement within your organization and to other appropriate mail lists.
More non-normative information about the specification and the technical committee may be found at the public home page of the TC at http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=search-ws. Comments may be submitted to the TC by any person through the use of the OASIS TC Comment Facility which can be located via the button marked "Send A Comment" at the top of that page, or directly at http://www.oasis-open.org/committees/comments/index.php? wg_abbrev=search-ws.
Submitted comments (for this work as well as other works of that TC) are publicly archived and can be viewed at http://lists.oasis-open.org/archives/search-ws-comment/. All comments submitted to OASIS are subject to the OASIS Feedback License, which ensures that the feedback you provide carries the same obligations at least as the obligations of the TC members.
