Integration with related schemas? about eml HOT 6 CLOSED

We have XSL stylesheets that translate EML to FGDC BDP and BDP to EML. Form SVN here:

https://code.ecoinformatics.org/code/eml/trunk/lib/eml2tonbii

There is also an EML to ISO19115 stylesheet I think as well, maybe started by GBIF. Can try to track it down if needed.

• Conversion from Biological Data Profile to EML: Added stylesheet: bdp2eml.xsl, yet not tested.
• Conversion from EML to ISO19139: Stylesheet added. Conversion working with EML 2.1.0. reml extended to optionally write in this legacy format, but ideally the stylesheet should be updated to acknowledge 2.1.1.

library(Sxslt)
a = xsltApplyStyleSheet("inst/examples/hf205.xml", "inst/xsl/eml2iso19139.xsl")

• Conversion from EML to BDP: added eml2tonbii.xsl, not working with Sxslt library yet. (xalan issue, see #53).
• Conversion from ESRI to EML: not tested.

@cboettig Note that we often have the issue of needing to convert from older versions of EML to newer ones. In Morpho, we've decided to always serialize the newest version, but to be able to read all of them. If a user wants to edit an EML document, we force them to forward-convert to the latest EML version, which reduces our maintenance load and makes it easier for tools to work together. To do that, we have XSLT stylesheets to convert from one version of EML to another:

https://code.ecoinformatics.org/code/eml/trunk/style/eml201to210.xsl
https://code.ecoinformatics.org/code/eml/trunk/style/eml201to211.xsl
https://code.ecoinformatics.org/code/eml/trunk/style/eml210to211.xsl

You may find these useful.

Awesome. Given that reml / our S4 structure is built on 2.1.1, would you recommend that eml_read attempt to detect the version and apply the conversion into 2.1.1 if necessary/possible before parsing? Or is that likely to introduce more headache than gain? In my limited experiments I haven't had trouble reading 2.1.0 into reml, which currently doesn't have the full 2.1.1 schema implemented yet anyhow...

You'll probably find that 2.0.x versions are essentially compatible, and 2.1.x versions are essentially compatible (only requiring a namespace change to the newer namespace), but that moving from 2.0.x to 2.1.x will require document transformations and may result in validation errors in some cases where the schema became more strict. An overview of the differences is available here:

Using existing XSLT stylesheets for conversion between standards is probably the way to go for this, but won't be wrapped into the EML package at this point. Such conversions can be done with R and omegahat SXSLT, but since SXSLT isn't on CRAN and this is a relatively straight-forward thing to do with other tools as well, will close this as out-of-scope for now. Certainly re-open if or when this should be revisited.
