[eml-dev] FW: EML and ISO19115

Mon Jan 17 08:55:37 PST 2011

Hi All,

Update: the latest version of the XSL file for translating from the GBIF EML
profile
(http://rs.gbif.org/schema/eml-gbif-profile/dev/eml-gbif-profile.xsd) to
ISO19139 is here:

http://code.google.com/p/gbif-metadata/source/browse/trunk/metadata/src/main
/resources/eml2iso19139.xsl. Please ignore the older URL below which is an
early version and does not produce valid ISO19139 documents.

We use EML and ISO19139 for just for discovery level metadata. As Inigo
points out, expressing the richer data level aspects of EML will be quite a
challenge, I think. But, at least, getting the equivalent of the FGDC
Biological Profile expressed in ISO19139 would be good, and I see that NOAA
has made a start on that
(http://www.ncddc.noaa.gov/technology/metadataandxml/view).

Happy holidays,

These days Ive been browsing the ISO19139 schemas (staying away from the
conceptual 19115, directly to the XML implementation).

I see lots of synergies between FGDC, ISO and EML, but still, let's be
clear, ISO19139 is a geospatial standard - so in practice, it does not cover
well any spreadsheet or regular RDBMS based data, nor views of RBDMS (most
of those can be described as views or spreadsheets). 

I looked and looked through most of the 62 schemas associated with the ISO
(the tags & hierarchy, really), and I still have to find the right niche for
descriptions of spreadsheets or physical measurements [variables]  (in EML,
those were named "attributes"..).  The stylesheet provided here (thanks!)
stops at the resource element -- that is, data discovery functionality at
best. 

Given that ISO19139 includes openGis's GML, this stylesheet could be
extended to cover the EML non-resource groups "spatialRaster/Vector". Even
witgh that addition, the crosswalk is limited by the limitations of the
source metadata (ISO) -- it would provide a bridge for GIS-centric data - it
would not help to all these studies that are non- GIS centric, and those
abound in biology.  While the move towards ISO19139/19115 or ISO/NAP may
make sense to GIS folks, including those users of FGDC's "Content Standard
for Digital Geospatial Metadata" and its profiles, the Biological Data
Profile (BDP) and so on, it does not make much sense to those who need to
describe spreadsheets and the like. Given that most geo-spatial applications
lean on Esri, ISO, Inspire or the products of FGDC, Im still unsure how
useful is going to be this crosswalk - but for compliance, and for what is
worth, this is good, and perhaps worth to extend to the GML part.  Other
folks have done great work in this, including Ted Habberman (NOAA) and
Wolfgang Grunberg (USGIN), who also did another Drupal based metadata wizard
with ISO compliance, etc.  Wolfgang and the USGIN group  actually wrote some
nice best practices and documents related to ISO. I didnt find any
complimentary standard sanctioned by ISO that covers what EML "dataTable"
section covers -- this would be great to have as an extension or compliment
for the ISO19139, etc. if any of you know where this stuff is, please point
me to it (no, im not looking for ODFs and the like, something simpler if
possible). I know you guys may have some great guidance into this.  Perhaps
after Santa Claus we can have some chat?  

Cheers, Inigo

GBIF has developed an XSLT to transform our profile of EML 2.1.0 to
ISO19139. It may provide a start for a more comprehensive stylesheet. See

We've wanted that for a long time, but I don't know of anyone who is working
on it directly. I think that this conversion would be a little easier than
the conversion to the BDP. Would this be something that the folks at ILTER
could tackle and make available through the EML project alongside the other
conversion XSLTs?

Matt et al,

I was wondering if there is a plan to create cross-walks between EML and
ISO19115.  All of the European LTERs will be required to report in ISO19115
format. An XSLT analogous to the EML to FGDC would be very inportant
