Dearest public LOD mailing list, I was looking for a specification, a bit like RSS, that would allow me to tell potential data consumers that: - I’m maintaining a collection of members adhering to a certain shape, - that they they can find and download all of the members, and - that I want them to stay in sync with the latest changes. As I did not find a solution in for example LDP, Hydra or Activity Streams 2, I made my own. You can find the Linked Data Event Streams (LDES) specification over here: https://w3id.org/ldes/specification. It does not do much: it just defined an event stream as a collection of an ever-growing collection of objects that never change (“version objects”). It is based on the TREE specification (https://w3id.org/tree/specification) which in its turn allows more than simple one-dimensional paging. It allows to make your collection searchable using qualified links to following pages (or tree:Nodes). This means you can for example geospatially tile your LDES [1] or expose a file-based substring index [2]. Of course, you can also just load the LDES in a triple store and make sure your copy always stays in sync with the authoritative data source. TREE also foresees compatibility with hypermedia specs and collection designs in LDP, Hydra, Activity Streams 2, Shape Trees and Triple Pattern Fragments. Over the coming months we are planing to publish some governmental base registries with this specification. Are there any other specs LDES should be compatible to? Kind regards, Pieter P.S. Tomorrow I’m speaking at this online event called ENDORSE about this specification and the ideas behind it. More info: https://op.europa.eu/en/web/endorse/programme [1] We last year published about a geospatial fragmentation in this paper: https://hdelva.be/articles/geospatial-linked-connections/ [2] Check out an autocompletion demo on top of a TREE collection fragmented by substring here: https://treecg.github.io/treemunica_typeahead_demo/ - I can send a preprint of a paper we wrote about this if interested. -- https://pietercolpaert.be/#me
