Going with the name emld: Ecological Metadata as Linked Data, since I think it is more useful to emphasize the ld side than the json side of the serialization here. For instance, one of the most immediate use cases of the json-ld serialization of EML is to dump it all into RDF and then extract the desired components with SPARQL queries.

In general I think emld can play much more of a role on the consuming EML (and possibly in modifying existing EML) where the current EML package requires a lot of @@@@@ subsetting and knowing where a particular piece of data is buried. The RDF route is one way to abstract that structure away and permit more semantic statements. Less involved, just jsonld_flattening the EML first may also be useful.
