This experiment takes two taxa for the same lizard (Geckonia chazaliae or Tarentola chazaliae) and runs a query to discover that these taxa are duplicates. In other words, GBIF has the same lizard twice in its classification.
Geckonia chazaliae (name) ion:614045
Geckonia chazaliae (taxon) gbif:2445625
Tarentola chazaliae (name) ion:1748852

| = Network versioning using relationnodes | |
| Recently there was a nice blog on versioning networks by Ian Robinson (http://iansrobinson.com/2014/05/13/time-based-versioned-graphs/[read it here]) on using identity nodes and separating structure from state. In this gist I'd like to put in my 2 cents by introducing another approach using _relationnodes_. This is more about structure of a network than about states of nodes, but it treats versioning differently. As Ian states in his blog, there's always a trade-off to be made, since versioning causes an extra load on storage and processing. | |
| == Relationnodes? | |
| === What are relationnodes? | |
| Relation nodes are intermediary nodes between two network nodes that represents the relation between the nodes. | |
| So, if A and B are two network nodes, instead of connecting them with a relationship of `[:RELTYPE]`, |
