Final report of IPET-DRC-IV released

IPET-DRC is an expert team in charge of maintenance of WMO Codes, such as
SYNOP, GRIB, or BUFR.
IPET-DRC held its fourth meeting in Exeter, UK from 21 to 25 May 2012; the
final report is now available from the WMO Web at:

ISO19139 memo - // trick to select MD_DigitalTransferOptions scattered around a record

In current ISO 19139, there are three places to hold URL with authority:
distributionInfo/*/distributor/*/distributorTransferOptions/*/onLine/*/linkage
and distributionInfo/*/transferOptions/*/onLine/*/linkage.

(Darn long path!)

distributorTransferOptions exists for situation in which a dataset has more
than one distributor and each has different linkage.
In other words, it is enough to use transferOptions (a) if there is only one
distributor or (b) if all distributor share the same linkage.

It is painful to prepare for two possibilities. But there is a trick. We
can select //onLine/*/linkage to get entire set of URL's. There is no risk
of selecting MD_DigitalTransferOptions located anywhere because it is only
allowed at these two places.

My involvement is really merginal though:

new metadata for World Data Centre for Greenhouse Gases

The World Data Centre for Greenhouse Gases (WDCGG), operated by Japan
Meteorological Agency, has moved to new website
http://ds.data.jma.go.jp/gmd/wdcgg/ effective 29th February 2012. So we've
re-generated WIS version metadata to reflect new URL structure. Now 1570
records are available.

You can browse list of records at GISC Tokyo:
http://www.wis-jma.go.jp/meta/search.jsp?oai_provider=0&text=WDCGG

You can also use GISC's SRU interface. This example searches CO2 observation
in sub-sahara Africa:
http://www.wis-jma.go.jp/meta/sru.jsp?version=1.1&operation=searchRetrieve&query=CO2+and+geo.bounds+within%2Fpartial%2Fnwse+%2220+-20+-45+50%22

And the good news is we have fixed URL link in metadata records, so the
catalogue now links to real data for example
http://ds.data.jma.go.jp/gmd/wdcgg/cgi-bin/wdcgg/accessdata.cgi?select=inventory&index=NMB123S00-NOAA

Metadata entry from Cambodia

On 22nd March, Department of Meteorology (DOM) of Cambodia has submitted an
metadata record describing their GTS bulletin SMKP01 VDPP.

This is a great step!

metadata records for GRIB data at GISC Cache Tokyo

I'm now publishing metadata records for GRIB data in two-tier structure.

== Tier 1: Per-bulletin record

Example: http://www.wis-jma.go.jp/meta/search.jsp?text=HVXO10RJTD

The record has two links in "identification info". One links to actual
data:

Example: http://www.wis-jma.go.jp/data/browse?Indicator=RJTD&LinkText=HVXO10

Another links to metadata of a product which the bulletin belongs to.

Example:
http://www.wis-jma.go.jp/meta/search.jsp?text=GSM25X&keywords=GRIB+Aggregate

== Tier 2: Per-product record

Here I define "product" as a set of GRIB bulletins that share code-form,
model, resolution, and spatial area.

Example:
http://www.wis-jma.go.jp/meta/search.jsp?text=GSM25X&keywords=GRIB+Aggregate

This one links to actual data in the product.

Example:
http://www.wis-jma.go.jp/data/browse?Type=GRIB&Discipline=Global+Spectral+Model&Resolution=2.5+2.5&Area=90.0+0.0+0.0+357.5
