GetCapabilities​

How to Get server metadata with "GetCapabilities" request

GET request

http://localhost:8080/csw?request=GetCapabilities&service=CSW

Query by IsEqualTo value​

How to query the catalog by specific property and his value

POST request

Url:
http://localhost:8080/csw

Content-Type
application/xml

Request body:
<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" maxRecords="1"  startPosition="1"
outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >
  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
        <PropertyIsEqualTo matchCase="true">
          <!-- ****** INSERT PROFILE FIELD NAME START ********************** -->
          <PropertyName>mc:productId</PropertyName>
          <!-- ****** INSERT PROFILE FIELD NAME END ********************** -->

          <!-- ****** INSERT PROFILE FIELD VALUE START ********************** -->
          <Literal>MAS_6_ORT</Literal>

        </PropertyIsEqualTo>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

Above example declare a query for mc:productId field in catalog and response with the full metadata of MAS_6_ORT match result.

maxRecords attribute in <csw:GetRecords></csw:GetRecords>element is equals to "1" means response will contain only 1 result.

startPosition will display records from all result start from the first one to the maxRecords value (1 to 1 in example).

Query by field value​

How to query the catalog by specific property and his value

POST request

Url:
http://localhost:8080/csw

Content-Type
application/xml

Request body:
<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" maxRecords="1"  startPosition="1"
outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >

        </PropertyIsLike>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

Above example declare a query for mc:productId field in catalog and response with the full metadata of MAS_6_ORT match result.

maxRecords attribute in <csw:GetRecords></csw:GetRecords>element is equals to "1" means response will contain only 1 result.

startPosition will display records from all result start from the first one to the maxRecords value (1 to 1 in example).

Query by field like value​

How to query the catalog by specific property to be like wild-card value

POST request

Url:
http://localhost:8080/csw

Content-Type
application/xml

Request body:
<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" maxRecords="5"  startPosition="1"
outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >
  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
        <PropertyIsLike wildCard="%" singleChar="_" escapeChar="\\">

          <!-- ****** INSERT PROFILE FIELD NAME START ********************** -->
          <PropertyName>mc:productId</PropertyName>
          <!-- ****** INSERT PROFILE FIELD NAME END ********************** -->

          <!-- ****** INSERT PROFILE FIELD VALUE START ********************** -->
          <Literal>%MAS_6_ORT%</Literal>
          <!-- ****** INSERT PROFILE FIELD VALUE END ********************** -->

        </PropertyIsLike>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

pay attention for the %MAS_6_ORT% in <Literal></Literal> element, now contains "%" after and before the value,

means CSW will look for every record that contains MAS_6_ORT value in mc:productId profile field

maxRecords equals to "5" means response will contain up to 5 results.

Number of records​

Get up to 5 records contains desired product version

<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" maxRecords="5"  startPosition="1"
outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >
  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
        <PropertyIsLike wildCard="%" singleChar="_" escapeChar="\\">

          <!-- ****** INSERT PROFILE FIELD NAME START ********************** -->
          <PropertyName>mc:productVersion</PropertyName>
          <!-- ****** INSERT PROFILE FIELD NAME END ********************** -->

          <!-- ****** INSERT PROFILE FIELD VALUE START ********************** -->
          <Literal>4.0</Literal>
          <!-- ****** INSERT PROFILE FIELD VALUE END ********************** -->

        </PropertyIsLike>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

another familiar example based on previous examples, just in that case we can see <PropertyName></PropertyName> element contains mc:productVersion means we query catalog records by their product version.

in this specific example we will get up to 5 records that includes productVersion of 4.0.

Query by Greater Or Equal​

ℹ️ ingestionDate = the date field that records will be filtered by.​

<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" startPosition="1"

  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
        <PropertyIsGreaterThanOrEqualTo>
      <!-- ****** INSERT PROFILE FIELD NAME START ********************** -->
      <PropertyName>mc:ingestionDate</PropertyName>
      <!-- ****** INSERT PROFILE FIELD NAME END ********************** -->

      <!-- ****** INSERT PROFILE FIELD VALUE START ********************** -->
      <Literal>2020-09-03T00:00:01Z</Literal>
      <!-- ****** INSERT PROFILE FIELD VALUE END ********************** -->

    </PropertyIsGreaterThanOrEqualTo>
  </Filter>
</csw:Constraint>

</csw:Query> </csw:GetRecords>

Response will contain up to 10 records (`maxRecords="10"`) that their **ingestion date** is Greater or Equal **2020-09-03T00:00:01Z**

```xml 
<PropertyIsGreaterThanOrEqualTo></<PropertyIsGreaterThanOrEqualTo>

to the record ingestion date in catalog.

Query by Less or Equal​

outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >
  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
        <PropertyIsLessThanOrEqualTo>
          <PropertyName>mc:ingestionDate</PropertyName>
          <Literal>2022-09-03T00:00:01Z</Literal>
        </PropertyIsLessThanOrEqualTo>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

Response will contain up to 10 records (maxRecords="10") that their ingestion date is Less or Equal 2022-09-03T00:00:01Z

<PropertyIsLessThanOrEqualTo></<PropertyIsLessThanOrEqualTo>

to the record ingestion date in catalog.

Query by multi fields​

Use <And></And> element to includes 2 or more conditions for Query catalog by multi fields:

<?xml version="1.0" encoding="UTF-8"?>
<csw:GetRecords xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" service="CSW" maxRecords="10"  startPosition="1"
outputSchema="http://schema.mapcolonies.com/raster" version="2.0.2" xmlns:mc="[SUB-SYSTEM-MAIN-NAMESPACE]" >
  <csw:Query typeNames="[SUB-SYSTEM-TYPENAME]">
   <csw:ElementSetName>full</csw:ElementSetName>
    <csw:Constraint version="1.1.0">
      <Filter xmlns="http://www.opengis.net/ogc">
      <And>
        <PropertyIsLike wildCard="%" singleChar="_" escapeChar="\\">
          <PropertyName>mc:productVersion</PropertyName>
          <Literal>4.0</Literal>
        </PropertyIsLike>
        <PropertyIsLessThanOrEqualTo>
          <PropertyName>mc:ingestionDate</PropertyName>
          <Literal>2022-09-03T00:00:01Z</Literal>
        </PropertyIsLessThanOrEqualTo>
      </And>
      </Filter>
    </csw:Constraint>
  </csw:Query>
</csw:GetRecords>

Response will contain up to 10 records (maxRecords="10") that includes product version "4.0" and their ingestion date is Less than the desired date 2022-09-03T00:00:01Z .
