16 Catalog Services for the Web (CSW) Support

This chapter describes the Oracle Spatial and Graph implementation of the Open GIS Consortium specification for catalog services. According to this specification: "Catalogue services support the ability to publish and search collections of descriptive information (metadata) for data, services, and related information objects. Metadata in catalogues represent resource characteristics that can be queried and presented for evaluation and further processing by both humans and software. Catalogue services are required to support the discovery and binding to registered information resources within an information community."

The Oracle Spatial and Graph implementation will be referred to as Catalog Services for the Web, or CSW

This chapter includes the following major sections:

Note:

Before you use CSW, be sure that you understand the concepts described in Chapter 10, "Introduction to Spatial Web Services", and that you have performed any necessary configuration work as described in that chapter.

If you have data from a previous release that was indexed using one or more SYS.XMLTABLEINDEX indexes, you must drop the associated indexes before the upgrade and re-create the indexes after the upgrade, as described in Section A.3.

16.1 CSW Engine and Architecture

This section describes CSW, including its relationship to clients and to the database server. CSW is implemented as a web service and can be deployed in a WebLogic Server, Oracle Application Server, or standalone Oracle Application Server Containers for J2EE (OC4J) environment.

CSW has a metadata layer, which stores in the database the metadata needed to reply to catalog requests. The metadata includes spatial columns, which can be queried and processed using Oracle Spatial and Graph interfaces. The metadata also stores the association of nonspatial and spatial attributes of records, as well as the services that the catalog service provides to its clients.

Figure 16-1 shows the CSW architecture.

Figure 16-1 CSW Architecture

Description of Figure 16-1 follows
Description of "Figure 16-1 CSW Architecture"

As shown in Figure 16-1:

  • CSW is part of a container in the Oracle Application Server middle tier.

  • CSW can communicate with a web service client using CSW requests and responses in SOAP/XML format.

  • CSW performs spatial data and metadata access through JDBC calls to the database.

  • The database includes Oracle Spatial and Graph with CSW metadata and data.

CSW security is implemented using secure transport. User identities and user labels are managed in LDAP, and the middle tier and CSW security combine to perform authentication. Oracle label-based security is used for managing user privileges at the record level.

16.2 CSW APIs and Configuration

The CSW APIs enable you to perform operations that include:

  • Specifying information about record type domains and record view transformations

  • Publishing record types

  • Dropping (unpublishing) record types

  • Granting to users and revoking from users privileges on CSW record types

Chapter 22 describes the PL/SQL API (SDO_CSW_PROCESS package), Section 16.3 provides examples of XML requests and responses, and Section 16.4 describes the Java API.

16.2.1 Capabilities Documents

A capabilities document describes an instance of a capability. The document specifies a record type and the type of operations supported (such as insert and delete).

A capabilities document is generated by the CSW server in response to a GetCapabilities request. The CSW server uses a capabilities template, and adds information about the record type and operations to this template to create the capabilities document.

The client can use the HTTP GET method to access this capabilities document using either the SOAP interface or the XML interface:

  • For the SOAP interface, use oracle.spatial.ws.servlet.CSWServlet, which can be accessed at an address in the following format:

    http:///machine-name:port/SpatialWS-SpatialWS-context-root/cswservlet?request=GetCapabilities&service=CSW&acceptversion=2.0.0&outputFormat=text/xml
    
  • For the XML interface, use oracle.spatial.ws.servlet.CSWXMLServlet, which can be accessed at an address in the following format:

    http:///machine-name:port/SpatialWS-SpatialWS-context-root/xmlcswservlet?request=GetCapabilities&service=CSW&acceptversion=2.0.0&outputFormat=text/xml
    

In the preceding formats:

  • machine-name is the name of the system where the application server or OC4J server is running.

  • port is the port number where the application server or OC4J server is running.

  • SpatialWS-SpatialWS-context-root is the default root where the Spatial and Graph web services application is mounted.

  • cswservlet is the servlet-mapping url-pattern for oracle.spatial.ws.servlet.CSWServlet, as specified by default in the web.xml file.

  • xmlcswservlet is the servlet-mapping url-pattern for oracle.spatial.ws.servlet.CSWXMLServlet, as specified by default in the web.xml file.

16.2.2 Spatial Path Extractor Function (extractSDO)

If you need CSW to process any spatial content that is not in GML format, you must create a user-defined function named extractSDO to extract the spatial path information. This function must be implemented for each record type that has spatial content in non-GML format and on which you want to create a spatial index. (This function is not needed if all spatial content for a record type is in GML format.)

This function must be registered, as explained in Section 16.2.2.1, so that the Oracle Spatial and Graph CSW server can find and invoke this function when it needs to extract spatial path content that is not in GML format.

The extractSDO function has the following format:

extractSDO(

     xmlData IN XMLType,

     srsNs IN VARCHAR2,

     spPathsSRSNSList IN MDSYS.STRINGLISTLIST);

     ) RETURN MDSYS.SDO_GEOM_PATH_INFO;

Parameters

xmlData

Data of the record instance from which spatial path information needs to be extracted.

srsNs

User-defined namespace of the spatial reference system (coordinate system) associated with the spatial data for the feature type. This namespace (if specified) is also used to generate the srsName attribute in the <boundedBy> element of the FeatureCollection result generated for the GetFeature request.

spPathsSRSNSList

If a record type has multiple user-defined spatial reference system namespaces associated with different spatial paths, this parameter specifies the list of spatial reference system namespace information corresponding to the different spatial paths specified during type registration. It is an object of type MDSYS.STRINGLISTLIST, which is defined as VARRAY(1000000) OF MDSYS.STRINGLIST, and where MDSYS.STRINGLIST is defined as VARRAY(1000000) OF VARCHAR2(4000). If a record type does not have multiple user-defined spatial reference system namespaces associated with different spatial columns, this parameter should be null.

In each MDSYS.STRINGLIST object, the first element is the spatial reference system namespace, and second element is the spatial reference system namespace alias (if any).

Usage Notes

This function parses the non-GML spatial content and returns an object of type MDSYS.SDO_GEOM_PATH_INFO, which is defined as follows:

(path     MDSYS.STRINGLIST,
 geom     SDO_GEOMETRY,
 arrindex NUMBER)

The path attribute specifies path to the spatial content that is to be extracted and stored in the geom attribute. It is an object of MDSYS.STRINGLIST, which is defined as: VARRAY(1000000) OF VARCHAR2(4000). The path attribute has the following pattern: MDSYS.STRINGLIST('pe_namespace1','pe_name1', 'pe_namespace2','pe_name2',...); where:

  • pe_namespace1 is the namespace of the first path element.

  • pe_name1 is the name of the first path element.

  • pe_namespace2 is the namespace of the second path element.

  • pe_name2 is the name of the second path element.

  • and so on, for any remaining namespace and name pairs.

In the path, /typeNameNSAlias:typeName/pe_namespace1_Alias:pe_name1/pe_namespace2_Alias:pe_name2... is an XPath representation of spatial content, in non-GML format, that will be extracted by the user-defined function extractSDO:

  • typeNameNSAlias is an alias to record type name namespace.

  • typeName is the type name of the record type.

  • pe_namespace1_Alias is a namespace alias for namespace pe_namespace1

  • pe_namespace2_Alias is a namespace alias for namespace pe_namespace2.

The geom attribute is the spatial content (corresponding to the path parameter) extracted as an SDO_GEOMETRY object. The extracted geometry can then be indexed using a spatial index.

The arrindex attribute is not currently used, and should be set to 1. (It is reserved for future use as an array index of paths.)

16.2.2.1 Registering and Unregistering the extractSDO Function

After you create the extractSDO function, you must register it to enable it to be used for processing spatial path content in record types that is not in GML format. To register the function, call the SDO_CSW_PROCESS.InsertPluginMap procedure. For example:

BEGIN
  SDO_CSW_PROCESS.insertPluginMap('http://www.opengis.net/cat/csw',
    'Record', 'csw_admin_usr.csw_RT_1_package');
END;
/

If you no longer want the extractSDO function to be used for processing spatial path content that is not in GML format, you can unregister the function by calling the SDO_CSW_PROCESS.DeletePluginMap procedure. For example:

BEGIN
  SDO_CSW_PROCESS.deletePluginMap('http://www.opengis.net/cat/csw', 
    'Record');
END;
/

16.3 Request and Response XML Examples

This section presents some record requests to the CSW engine, and the response to each request, for each of the following operations:

  • GetCapabilities

  • DescribeRecord

  • GetRecords

  • GetDomain

  • GetRecordById

  • Transaction, with a subelement specifying the transaction type:

    • Insert

    • Update

    • Delete

Example 16-1 is a request to get the capabilities of the CSW server named CSW at a specified namespace URL. T.his request will return a capabilities document, as explained in Section 16.2.1

Example 16-1 GetCapabilities Request

<csw:GetCapabilities service="CSW" xmlns:csw="http://www.opengis.net/cat/csw" xmlns:ows="http://www.opengis.net/ows">

Examples of record type path registration metadata XML are provided in rt_metadata1.xml and rt_metadata2.xml. These files are included in the ws_client.jar demo file (described in Section 10.4) under the src/data/ path. For information about using the examples to publish record types, see the Readme.txt file, which is included in ws_client.jar under the src/ path.

typeNS is the URL of the namespace of the record type.

typeName is the name of the record type.

idPaths is a list of record ID path elements where each element is a String.

srsPaths is a list of paths representing spatial reference system information.

idExtractorType is Identifier extractor method information (XPATH, USER_FUNC, or NONE). XPATH means that the record identifier will be extracted using an XPath as specified in the idPaths parameter. USER_FUNC means that the record identifier will be extracted by a user-defined function invocation, as specified in the idPaths parameter, to which the entire record document instance will be passed. NONE means that the record identifier will be a system-generated identifier.

sdoMetaInfo is the spatial metadata information for spatial paths. It is an ArrayList of class oracle.spatial.ws.GeomMetaInfo, which is described in Section 16.4.12.1.

srsNSAlias is the namespace alias of the spatial reference system (coordinate system) associated with the data in the spatial paths.

rtXSDRefId is the group record type XML schema definition file name (as a string), for cases where multiple record types are defined in a single XSD file. This parameter is used to store the group XSD definition once in the CSW metadata, and then refer to it from multiple record types whose schema definitions are present in the group record type XSD file.

genSpatialIndex is a Boolean value: TRUE causes a spatial index to be created on the record type at type creation time; FALSE does not cause a spatial index to be created.

setDomainInfo is a Boolean value: TRUE causes domain information for this record type to be set at type creation time; FALSE does not cause domain information for this record type to be set.

domainInfo is domain information.

setRecordViewMap is a Boolean value: TRUE causes the record view transformation map to be set at type creation time; FALSE does not cause the record view transformation map to be set.

recordViewMap is the record view transformation map information (brief to full, summary to full, and dcmi to full). It is of type ArrayList<ArrayList<Object>> where the content of each ArrayList<Object> is: Object[0] = (String) recordTypeNS, Object[1] = (String) viewSrcName, Object[2] = (String) targetTypeName, Object[3]= (oracle.xdb.XMLType) mapInfo, Object[4] = (String) mapType

numPaths is a list of numeric (NUMBER, INTEGER, and so on) related paths in the record type. It is an ArrayList of class oracle.spatial.ws.PathInfo, which is described in Section 16.4.12.1.

idxPaths is the index path list. It is list of paths on which to create an index of type XDB.XMLINDEX when that index is created. It is an ArrayList of class oracle.spatial.ws.PathInfo, which is described in Section 16.4.12.1.

oracle.spatial.ws.PathElement is a Java class that contains a pair of String objects: the PathElement namespace am the PathElement name. This class includes the getValue() method, which returns a string format of the PathElement object. This class has the following format:

public class PathElement {
// Set namespace and name information for a PathElement.
        public void set(String ns, String name);
 //Get a string value for the PathElement object.
        public String getValue() ;
}

oracle.spatial.ws.Path is a Java class that contains an ordered list of PathElement objects that constitute the path. For example, if an XPath is myns:A/myns:B, then myns:A and myns:B are PathElement objects. This class includes the getValue() method, which returns a string format of the Path object. This class has the following format:

public class Path {
//Add a PathElement.
        public void add(PathElement p) ;
//Get a string Value for the Path object.
        public String getValue() ;
}

oracle.spatial.ws.PathInfo is a container class that contains information about a path or list of paths, including their association and metadata information. This class has the following format:

  // related to each other via choice association. For example, we may have
  // a list of Spatial Paths, which are associated with one another via choice.
  // So, only one of these path can occur in a feature instance/document.
  // PathInfo.COLLECTION - means the list of paths in this PathInfo are part 
  // of a collection (currently spatial collections are 
  // supported) which will be indexed.
  // Default value is PathInfo.DEFAULT for one Path or a finite array Paths.
  //  @param t PathInfo type information. PathInfo.CHOICE or
