Microformat for PolarGrid -- Amendment

Thanks to William for a concrete example, and the request of including units in microformats, here comes the revision:

• Simple descriptive metadata:

<span class="pg:antenna">
<span class="pg:id">0</span>

</span>
</span>



• Sample delay:
  
<span class="pg:delay>
<span class="pg:value">0</span>
<span class="pg:unit">us</span>
</span>



• Blanking time:

<span class="pg:unit">us</span>
</span>



• Data acquisition unit:
  
<span class="pg:data-acquisition-unit">
<span class="pg:id">0</span>

</span>
</span>
</span>



• Spatial and temporal information of a data processing chunk. Note that existing geo microformat is used, which is outside our pg namespace:
  
<span class="pg:data-chunk">
<span class="pg:name">Start/Stop</span>
<span class="pg:utc-timestamp">1202755351.892651</span>

<span class="latitude">52.686</span>
</span>
</span>



• Individual waveform identification:
  
<span class="pg:waveform">
<span class="pg:id">1</span>
</span>



• Individual (jpg) file:
  
<span class="pg:data-file">
<span class="pg:name">MCRDS_20070917_113924_fk_image_wf_01_tx_01_rx_01.jpg</span>
