Re: [Java-dev] XML Standards

Here is an example of what we have been using, we have a queryable
service.  Here's the current result from the request

<?xml version="1.0" encoding="UTF-8"?>
<response version="1.0">
  <data_source name="metars" />
  <request type="retrieve" />
  <errors />
  <warnings />
  <data num_results="1">
      <raw_text>KDEN 231653Z 27020G28KT 10SM FEW080 SCT120 BKN160 11/M05
A2993 RMK AO2 PK WND 27028/1650 SLP097 ACSL DSNT S T01061050</raw_text>
        <cloud_condition sky_cover="FEW" cloud_base_ft="8000" />
        <cloud_condition sky_cover="SCT" cloud_base_ft="12000" />
        <cloud_condition sky_cover="BKN" cloud_base_ft="16000" />

If you are interested, you can take a look at what we're doing at

We are trying to bring our formats in line with the rest of the
community, but the community itself is so fragmented that I have yet to
find a real standard.  We have the option of providing data in multiple
formats, but I feel that that would fragment groups even further.  I
would prefer to adopt a single standard and try to unify what people are
using.  Our format was modeled in form after what the NWS is publishing,
but their format is for human-readable purposes (RSS) and ours is for
bare data access so our content differs.  I have been talking with Bob
Bunge from the NWS, and I am waiting to hear his opinion on the WMO

So if you know of any other widely-adopted formats, I'd be happy to hear
about them.  Another format I came across was the Navy's OMF.
http://www.metnet.navy.mil/Metcast/XML/OMF.html  I haven't looked into
that one in enough detail to comment on it.
