Yingshou,
The definition of categories now needs to be part of the las.xml file.
Here's an example from our NVODS server that includes several different
category.xml files:
...
<!ENTITY institute SYSTEM "Institution_cat.xml">
<!ENTITY dataset SYSTEM "Dataset_cat.xml">
<!ENTITY temporal SYSTEM "Temporal_cat.xml">
<!ENTITY discipline SYSTEM "Discipline_cat.xml">
<!ENTITY source SYSTEM "Source_cat.xml">
]>
<lasdata>
<las_categories>
&dataset;
&temporal;
&source;
&discipline;
</las_categories>
...
The individual files like "Dataset_cat.xml" just list the categories:
<category name="by Dataset Name">
<category name="DAO 4D AMM One Layer Diagnostic Data"
doc="http://daac.gsfc.nasa.gov/CAMPAIGN_DOCS/FTP_SITE/INT_DIS/readmes/assim54A_mo_subset.html#200">
<filter action="" equals="DAO 4D AMM One Layer
Diagnostic Data"/>
</category>
...
</category>

* * * Announcing LAS version 6.2 * * *
Version 6.2 of the Live Access Server is now available from the LAS
downloads page.
http://ferret.wrc.noaa.gov/Ferret/LAS/Downloads/
Please try out this new release and contact us with any problems you
encounter.
We would also like to take this opportunity to let you know that Joe
Sirott, chief architect and developer of LAS for the last few years,
has left the TMAP group to pursue other opportunities. Joe's skills
and effort have played a huge role in making LAS into what it is today
and future developments will no doubt benefit from the flexible and
robust base of code he has left us with. Thanks, Joe. We hope that
his current and future projects turn out equally well.
