Indexing Procedure

The Indexing procedure refers to the creation of indices for the collections imported in a Virtual Organization. It consists of three steps:

Creation of the Rowset XSLT generic resources, that transform collection data into data that can be fed to an Index.
Creation of the Index type generic resources, that define the Index configuration.
Definition of an IRBootstrapper job that will perform the steps required to create the Indices.

In the first two steps we create generic resources for the Rowset XSLTs and Index Types through the Resource Management portlet . You can find detailed descriptions for the Rowset data (the output of the Rowset XSLT transformation) in the following section:

Full Text Index Rowset

You can find detailed descriptions for the Index Type definition here:

Full Text Index Type

For the third step, a definition of an IRBootstrapper job is required. You can find the details for defining such a job in the IR Bootstrapper section. To complete the Index creation, the administrator must go to the IRBootstrapper and run the job. The two examples that follow will clarify the three steps.

Creating an Index for an OAI-DC collection

DataTransformation Programs

FtsRowset_Transformer

The following transformation program is called for fulltext rowset creation. Transformation unit with id="6" takes multiple XSLTs and applies final XSLT at the end.

File:FtsRowset Transformer.xml

Index Types

In this section we present the required IndexType for (FullText) Index.

FullTextIndexType

In order to extract the fields from the OAI-DC payload and build the FullText Index the following FullTextIndexType is required:

<Name>IndexType_ft_oai_dc_1.0</Name>
<SecondaryType>FullTextIndexType</SecondaryType>
<Description>Definition of the fulltext index type for the 'oai dc' schema</Description>

Bootstrapper Configuration

The IRBootstrapper portlet requires a Generic Resource to be available on the IS with name: IRBootstrapperConfiguration and secondary type: IRBootstrapperConfig. For more information please refer to this section IRBoostrapperConfiguration Generic Resource

An example of the configuration is the following:

File:Bootstrapper Configuration.xml

Metadata Broker XSLT

BrokerXSLT_oai_dc_anylanguage_to_ftRowset_anylanguage

The following XSLT transforms data elements with oai-dc schema to fulltext rowsets:

File:BrokerXSLT oai dc anylanguage to ftRowset anylanguage.xml

 For the third step, a definition of an IRBootstrapper job is required. You can find the details for defining such a job in the [[ IR Bootstrapper ]] section. To complete the Index creation, the administrator must go to the IRBootstrapper and run the job. The two examples that follow will clarify the three steps.

-Additionally we must create the corresponding Full Text Index Type for the fields extracted from the ES and DC payload:
+=== Bootstrapper Configuration ===
+The IRBootstrapper portlet requires a Generic Resource to be available on the IS with name: '''IRBootstrapperConfiguration''' and secondary type: '''IRBootstrapperConfig'''.
+For more information please refer to this section [https://gcube.wiki.gcube-system.org/gcube/index.php/IR_Bootstrapper#Bootstrapper_Static_Configuration IRBoostrapperConfiguration Generic Resource]
-Name := IndexType_ft_es_dc_2.0

-Description := Definition of the fulltext index type for the 'es' + 'dc' schema

-Note, in the Index Type above, that we also need to define the default "gDocCollectionID" and "gDocCollectionLang" fields, although there are not referenced in the XSLTs(the are automatically added by the [[ Data_Transformation | DTS ]] ).
-Then we will create the generic resources for the Forward Index. We will present a simple case here and we will use only the ES payload to create the Forward Rowsets. The following Rowset XSLT extracts the "title" and "creator" fields from the ES payload:
-Name := BrokerXSLT_es_anylanguage_to_fwRowset_anylanguage_title_creator
-SecondaryType := MetadataBrokerXSLT
-Description := XSLT to transform from es schema to forward rowset schema including the 'title' and 'creator' fields (suitable for feeding the forward index).

-In this example "title" and "creator" will have string values, so we just need to create a generic resource for string-string key-value pairs:
-Name := IndexType_fwd_string_string
-SecondaryType := ForwardIndexType
-Description := Definition of the index type 'string_string' for the forward index
-Body :=
-<source lang="xml">
-         <field-list>
-            <field name="key">
-               <type>string</type>
-               <sort>ascending</sort>
-            </field>
-            <field name="value">
-               <type>string</type>
-            </field>
-         </field-list>
-</source>
-In case we had a field that would have a single date value in the format 'yyyy-MM-dd' for each document, we would also have to create a generic resource for a string-date key-value pair like the following one:
-Name := IndexType_fwd_esDate_string
-SecondaryType := ForwardIndexType
-Description := Definition of the index type 'date_string' for the forward index (suitable for es schema indexing)
-Body :=
-<source lang="xml">
-         <field-list>
-            <field name="key">
-               <type>date</type>
-               <format>yyyy-MM-dd</format>
-               <sort>ascending</sort>
-            </field>
-            <field name="value">
-               <type>string</type>
-            </field>
-         </field-list>
-</source>
-Finally we would have to append to the IRBootStrapper configuration generic resource the following job that would create the Full Text and Forward Index:
-<source lang="xml">

-where the jobtype is defined in the corresponding section of the IRBootstrapper configuration:

-Note in the IRBootstrapper job, that for the Forward Index we additionally define the default fields ObjectID, gDocCollectionID and gDocCollectionLang which are all of string-string type.
-==Creating a Geo-Spatial Index for a collection with ES payload==
