Hi Tom, thanks for you report!
>From your gist [1] I see you are using Marmotta 3.2.1 where the LDP implementation was still very fresh and also the spec changed in the meantime. I tried to reproduce your errors with the current development snapshot and got ETag headers on all requests. Please try again with the current development version (or wait for the 3.3.0 release which is targeted for next week) Best, Jakob [1] https://gist.github.com/no-reply/1939bc67b69e171d1ceb On 5 November 2014 23:15, Tom Johnson <[email protected]> wrote: > Hi all, > > I'm trying to build a lightweight CRUD wrapper for LDP resources, and I'm > having a little trouble getting it to work well with Marmotta. > > I'm able to create containers and resources without much trouble, but start > hitting HTTP 428 responses.
