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
