Dear all,

Warning regarding Memento: the more programs one has to go through to get to the data, the harder the long-term preservation.

Disclaimer: I like Memento -:). I was in a presentation a few years ago; I think it was a IETF meeting is Maastricht.

Hi all,

With regard to Data versioning
<http://www.w3.org/TR/dwbp/#dataVersioning>, it seems to me it would
be good to take the existence of the Memento protocol (RFC 7089) [1]
into account when temporal versions are considered.

The Memento protocol specifies various approaches to support
recognizing and accessing temporal resource versions, including:
- the Memento-Datetime header used to convey version datetime of a resource
- a so-called TimeMap, which is a list of resource versions.

A simple description of how the Memento protocol relates to resource
versioning is available at [2].
