I would support that effort. Multiple incompatible syslog formats are a pain, and it has bitten me several times in multiple jobs. One approach that would be easy to move forward with is that you write a document registering a MIME media sub-type, e.g., text/syslog or application/syslog. Describing one reasonable syslog text format in that document. With this approach, there is less pressure on all syslog vendors to agree on a particular format, and you can just invent one format that makes sense and let people adopt it on an opt-in basis. I've registered some MIME media types, and learned some details when doing that, so I could help with this approach if you want. Having a MIME media type specified would also enable reliable transfer of syslog data in protocols that are MIME aware (e.g., HTTP or e-mail). With this approach, there is also less of a requirement to be backwards compatible with existing (often sub-optimal) formats. /Simon
