Hi Herbert, > >(1) vocabulary versioning > >The Memento-related comments I made about Data Versioning apply >equally to Vocabulary Versioning. All approaches described in ><http://mementoweb.org/guide/howto/> apply to data and vocabulary. As >a matter of fact, when implementing Memento protocol support for both >data and vocabularies used in data, temporal versions of the data can >automatically be aligned with the temporally correct version of the >used vocabulary. > Right now the Best Practices document classifies Data Versioning as a part-of/child-component within the Metadata parent topic. This can be seen within the taxonomy provided within the BP document ToC [0]. To me there is a distinction to me made here which indicate that your Momento-related comments do not necessarily apply equally to both Data versioning and Vocab versioning. The Momentos themselves e.g. The instances of archived versions of web resources could provide a Memento-Datetime which may be different from that published within and unique to the dataset. We need complete and utter clarification on this topic, however AFAICT the DWBP WG is taking a data centric view of data versioning meaning that a protocol which defines the data version would be more part of the BP relating to ³Follow REST principles when designing APIs² [1]. I think we need to be aware of the differences between something like Memento (a specification and protocol for accessing resources) and best practice of publishing versioning information alongside dataset which are to be published on to the Web. Thank you very much for your comments Herbert. Working Group is it worth visiting some aspects of the data versioning commentary and use cases at one of the forthcoming meetings?
