Set attributes for properties, e.g. `<title xml:lang="eng">`

[peterdesmet]

Is it possible to define attributes for properties? My use case is that I want to generate an EML file that can be uploaded and understood by a GBIF IPT. The IPT has a particular way of setting userId, by assigning a directory attribute. Is there a way to replicate that (in e.g. set_responsibleParty)?

<creator>
  <individualName>
    <givenName>Peter</givenName>
    <surName>Desmet</surName>
  </individualName>
  <userId directory="http://orcid.org/">0000-0002-8442-8025</userId>
</creator>

Ha, I see this is a duplicate of #338. Closing here.

@peterdesmet I think this is different from #338, which addresses attributes inside of additionalMetadata, which is handled differently from the rest of the EML schema. The @directory attribute is a standard part of the EML schema on the userId elelment and should be able to be set without a problem. We use it exactly as you described in our documents in the Arctic Data Center (it is recommended best practice for ORCIDs). The one difference is that DataONE, LTER, and other networks have converged on using the full ORCID in the userId value. Here's an example with directory set correctly:

me <- list(
    individualName = list(
        givenName = "Peter", 
        surName = "Desmet"), 
    userId = list(
        directory="https://orcid.org/", 
        'https://orcid.org/0000-0002-8442-8025'))
eml <- list(dataset = list(
    title = "dataset title",
    contact = me,
    creator = me),
    system = "doi",
    packageId = "10.xxx")
doc <- as_emld(eml)
eml_validate(doc)

Oh excellent! Thanks!
