IX. Data Server Configuration
A. Data services ThebackboneofthePacIOOSdatasystemisthedataservice.Ontheback-endofthissystemisanOPeNDAP-basedarchitecture.Inthissection,thedatatransporttoolsaredescribed.
1. TDS
a) configuration Therearetwodifferenttypesofconfigurationfilesthatareimportant.Thefirst,threddsConfig.xml,isfortheTDSoperations.TheotherconsistsofsetsofXMLfilesthatcomprisethedatacatalog.Themaincatalogiscatalog.xml.Thisfilecontainsdescriptionsofallthedatatobeserved,eitherbydirectlyspecifyingthedatasetname(andpath)orbyspecifyingsomeotherserver,orbyspecifyingasub-catalog.Forexample,theentry
<datasetRoot path="my/test" location="/export/lawelawe1/" /> <dataset name="Levitus" ID="levitus" urlPath="my/test/levitus.nc" > <serviceName>thisDODS</serviceName> </dataset>
specifiestheNetCDFfilelevitus.nc(specifiedwiththeurlPathtag),foundinthedirectory/export/lawelawe1(specifiedwiththelocationtag).ThedatasetwillshowupontheTHREDDSpageunderthelink"Levitus"(specifiedbythenametag).TheIDandpathtagsareusedtouniquelyidentifythedataset.Asub-catalogisspecifiedinthecatalog.xmlfilewithacatalogReftag,e.g.,
<catalogRef xlink:href="idd/roms\_scalar.xml" xlink:title="ROMS scalar vars" name="" />
Thexlink:hreftagspecifiesthelocationandnameofthenewcatalog(notethedirectory/usr/local/tomcat/content/thredds/iddcontainsallthesesub-catalogs).Again,thexlink:titletagiswhatshowsupontheTDSwebpage(asalinktotheDAPpage).
214
Theinitialsub-catalogsthathavebeendevelopedareforthemodeloutput,andrequiredsomespecialcodeforthenon-standardgridandvariables.Forexample,theroms_scalar.xmlfilestartswiththefollowingheaderinformation:
<?xml version="1.0" encoding="UTF-8"?> <catalog name="HI-ROMS Catalog" xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0" xmlns:xlink="http://www.w3.org/1999/xlink"> <service name="allServices" base="" serviceType="compound"> <service name="dapService" serviceType="OpenDAP" base="/thredds/dodsC/"/> <service name="wcs" serviceType="WCS" base="/thredds/wcs/"/> <service name="wms" serviceType="WMS" base="/thredds/wms/"/> <service name="ncss" serviceType="NetcdfSubset" base="/thredds/ncss/grid/"/> </service>
Therestofthexmlfiledefinesadatasettag,whereinthemetadata,linknamesandvariablesaredefinedorre-defined).Forexample:
<dataset name="HI-ROMS Nowcast/Forecast Test"> definesthenameattribute(thisshowsupastextontheTDSpageforthisdatasetasmoreorlessatitle).Thisisfollowedbysomemetadataattributes.ThecriticalnextpartisthedatasetFMRCtag:

ThefirstlinecontainsthetextthatwillshowupasthelinktotheDAPpage(i.e.,"HI-ROMSForecastModelTest"willbedisplayed).Thescanlocationtaggivesthedirectorywherethedataare,withattributessuffixthewildcardand
215

eta (xi_rho,eta_rho)T,s (xi_rho,eta_rho,s_rho)u (xi_u,eta_u,s_rho)v (xi_v,eta_v,s_rho)w (xi_rho,eta_rho,s_w)
andtheassociatedxml(onevariableexample)is:
<variable name="xi_rho" shape="xi_rho" type="double"> <attribute name="units" value="degrees_east"/> <values start="-163.83069727891120" increment="0.03860544217687"/> </variable>
Finally,thexmlfilecan"hide"acertainnumberofvariablesfromtheserver(variablesthatpeopletypicallydon'tneed):
<remove type="variable" name="ubar"/> <remove type="variable" name="DU_avg1"/> <remove type="variable" name="DU_avg2"/>
willhidethevariablesubar,DU_avg1andDU_avg2fromtheTDSlist.
b) example usage OncetheTDSisconfigured,itrestartswithtomcat(oritcanbedeployedwiththetomcatadminpage).ThetopcatalogforTDS,catalog.html,listsallthedatagroups(Figure25).Thedatagroupsaredefinedin/usr/local/tomcat/content/thredds/catalog.html.Selectingoneofthecategoriesbringsupamorespecificpageforthatdatacategory.Thesedata-specificpagesaredefinedin/usr/local/tomcat/content/thredds/idd/*.xml.
