Format-specific indexers in the Resource Management System
This topic describes the format-specific indexers used by MakePRI.exe to generate its index of resources.
This topic is referenced in the Compiling resources (MakePRI.exe) section of the Resource Management System topic.
MakePRI.exe, in its typical operation using the new, versioned, or resourcepack options, indexes source files to generate its index of resources. MakePRI.exe uses various individual indexers to read different resource files or containers for resources. The simplest indexer is the folder indexer, which indexes the contents of a folder, such as .jpg or .png images.
You identify format-specific indexers by specifying <index-config> elements within an <index> element. The type attribute identifies the format-specific indexer that is used.
Resource containers encountered during indexing usually get their contents indexed rather than being added to the index themselves. For example, .resjson files found with the folder indexer may be further indexed by a .resjson indexer, in which case the .resjson file itself does not appear in the index. Typically, qualifiers found on a containing entity, such as a folder, are applied to all resources within it, such as the strings in a resource file.
Folder
The folder indexer is identified by a type attribute of FOLDER. It indexes the contents of a folder, and determines resource qualifiers from the folder and filenames. Its configuration node conforms to following schema:
<xs:schema attributeFormDefault=\"unqualified\" elementFormDefault=\"qualified\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\">\
<xs:simpleType name=\"ExclusionTypeList\">\
<xs:restriction base=\"xs:string\">\
<xs:enumeration value=\"path\"/>\
<xs:enumeration value=\"extension\"/>\
<xs:enumeration value=\"name\"/>\
<xs:enumeration value=\"tree\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:complexType name=\"FolderExclusionType\">\
<xs:attribute name=\"type\" type=\"ExclusionTypeList\" use=\"required\"/>\
<xs:attribute name=\"value\" type=\"xs:string\" use=\"required\"/>\
<xs:attribute name=\"doNotTraverse\" type=\"xs:boolean\" use=\"required\"/>\
<xs:attribute name=\"doNotIndex\" type=\"xs:boolean\" use=\"required\"/>\
</xs:complexType>\
<xs:simpleType name=\"IndexerConfigFolderType\">\
<xs:restriction base=\"xs:string\">\
<xs:pattern value=\"((f|F)(o|O)(l|L)(d|D)(e|E)(r|R))\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:element name=\"indexer-config\">\
<xs:complexType>\
<xs:sequence>\
<xs:element name=\"exclude\" type=\"FolderExclusionType\" minOccurs=\"0\" maxOccurs=\"unbounded\"/>\
</xs:sequence>\
<xs:attribute name=\"type\" type=\"IndexerConfigFolderType\" use=\"required\"/>\
<xs:attribute name=\"foldernameAsQualifier\" type=\"xs:boolean\" use=\"required\"/>\
<xs:attribute name=\"filenameAsQualifier\" type=\"xs:boolean\" use=\"required\"/>\
<xs:attribute name=\"qualifierDelimiter\" type=\"xs:string\" use=\"required\"/>\
</xs:complexType>\
</xs:element>\
</xs:schema>
The qualifierDelimiter option specifies the character after which qualifiers are specified in a filename, ignoring the extension. The default is ".".
ResJSON
The ResJSON indexer is identified by a type attribute of RESJSON. It indexes the contents of a .resjson file, which is a string resource file. Its configuration node conforms to following schema:
<xs:schema id=\"resjson\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" elementFormDefault=\"qualified\">\
<xs:simpleType name=\"IndexerConfigResJsonType\">\
<xs:restriction base=\"xs:string\">\
<xs:pattern value=\"((r|R)(e|E)(s|S)(j|J)(s|S)(o|O)(n|N))\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:element name=\"indexer-config\">\
<xs:complexType>\
<xs:attribute name=\"type\" type=\"IndexerConfigResJsonType\" use=\"required\"/>\
<xs:attribute name=\"initialPath\" type=\"xs:string\" use=\"optional\"/>\
</xs:complexType>\
</xs:element>\
</xs:schema>\
A .resjson file contains JSON text as specified at The application/json Media Type for JavaScript Object Notation (JSON). The file must contain a single JSON object with hierarchical properties. Each property must either be another JSON object or a string value.
JSON properties with names that begin with an underscore ("_") are not compiled into the final PRI file, but are maintained in the log file.
The file can also contain "//" comments which are ignored during parsing.
The initialPath attribute places all resources under this initial path by prepending it to the name of the resource. You would typically use this when indexing class library resources. The default is blank.
ResW
The ResW indexer is identified by a type attribute of RESW. It indexes the contents of a .resw file, which is a string resource file.
Its configuration node conforms to following schema:
<xs:schema id=\"resw\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" elementFormDefault=\"qualified\">\
<xs:simpleType name=\"IndexerConfigResxType\">\
<xs:restriction base=\"xs:string\">\
<xs:pattern value=\"((r|R)(e|E)(s|S)(w|W))\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:element name=\"indexer-config\">\
<xs:complexType>\
<xs:attribute name=\"type\" type=\"IndexerConfigResxType\" use=\"required\"/>\
<xs:attribute name=\"convertDotsToSlashes\" type=\"xs:boolean\" use=\"required\"/>\
<xs:attribute name=\"initialPath\" type=\"xs:string\" use=\"optional\"/>\
</xs:complexType>\
</xs:element>\
</xs:schema>\
The ResW file is an XML file that conforms to the following schema:
<xsd:schema id="root" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xsd:import namespace="http://www.w3.org/XML/1998/namespace" />

</xsd:complexType>
</xsd:element>
</xsd:choice>
</xsd:complexType>
</xsd:element>
</xsd:schema>
The convertDotsToSlashes attribute converts all dot (".") characters found in resource names (data element name attributes) to a forward slash "/", except when the dot characters are between a "[" and "]".
The initialPath attribute places all resources under this initial path by prepending it to the name of the resource. You typically use this when indexing class library resources. The default is blank.
ResFiles
The ResFiles indexer is identified by a type attribute of RESFILES. It indexes the contents of a .resfiles file.
Its configuration node conforms to following schema:
<xs:schema id=\"resx\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" elementFormDefault=\"qualified\">\
<xs:simpleType name=\"IndexerConfigResFilesType\">\
<xs:restriction base=\"xs:string\">\
<xs:pattern value=\"((r|R)(e|E)(s|S)(f|F)(i|I)(l|L)(e|E)(s|S))\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:element name=\"indexer-config\">\
<xs:complexType>\
<xs:attribute name=\"type\" type=\"IndexerConfigResFilesType\" use=\"required\"/>\
<xs:attribute name=\"qualifierDelimiter\" type=\"xs:string\" use=\"required\"/>\
</xs:complexType>\
</xs:element>\
</xs:schema>\
The ResFiles file is a text file containing a flat list of file paths. A .resfiles file can contain “//” comments.
Example
Strings\component1\fr\elements.resjson
Images\logo.scale-100.png
Images\logo.scale-140.png
Images\logo.scale-180.png
PRI
The PRI indexer is identified by a type attribute of PRI. It indexes the contents of a PRI file. You typically use it when indexing the resource contained with another assembly, DLL, SDK, or class library into the app's PRI.
All resource names, qualifiers and values contained in the PRI file are directly maintained in the new PRI file. The top level resource map however is not maintained in the final PRI. Resource Maps are merged.
<xs:schema id=\"prifile\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" elementFormDefault=\"qualified\">\
<xs:simpleType name=\"IndexerConfigPriType\">\
<xs:restriction base=\"xs:string\">\
<xs:pattern value=\"((p|P)(r|R)(i|I))\"/>\
</xs:restriction>\
</xs:simpleType>\
<xs:element name=\"indexer-config\">\
<xs:complexType>\
<xs:attribute name=\"type\" type=\"IndexerConfigPriType\" use=\"required\"/>\
</xs:complexType>\
</xs:element>\
</xs:schema>\
PRIINFO
The PRIInfo indexer is identified by a type attribute of PRIINFO. It indexes the contents of a detailed dump file. You produce the dump file by using the dump command from MakePri.exe, with the detailed dump type option. The configuration node for the indexer conforms to the following schema:
<xs:schema id="priinfo" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigPriInfoType">
<xs:restriction base="xs:string">
<xs:pattern value="((p|P)(r|R)(i|I)(i|I)(n|N)(f|F)(o|O))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigPriInfoType" use="required"/>
<xs:attribute name="emitStrings" type="xs:boolean" use="optional"/>
<xs:attribute name="emitPaths" type="xs:boolean" use="optional"/>
</xs:complexType>
</xs:element>
</xs:schema>
The configuration node allows for optional attributes to configure the behavior of the PriInfo indexer. If emitStrings or emitPaths are not specified, the default behavior is to treat them as being set to true. Setting emitStrings to true causes resource candidates with the "type" attribute set to "String" to be included in the index. Setting emitStrings to false causes these values to be excluded from the index. Setting emitPaths to true causes resource candidates with the "type" attribute set to "Path" to be included in the index. Setting emitPaths to false causes these values to be excluded from the index.
Here is an example configuration that includes String resource types but skips Path resource types: <indexer-config type="priinfo" emitStrings="true" emitPaths="false" />
To be indexed, a dump file must end with the extension .pri.xml and must conform to the following schema:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" >\
<xs:simpleType name="candidateType">\
<xs:restriction base="xs:string">\

MakePri.exe supports dump types: detailed, basic, and schema. To configure MakePri.exe to emit the dump type that the PRIInfo indexer can read, include "/DumpType Detailed" when using the dump command.
Note The dump type schema is new for Windows 8.1.
Several elements of the .pri.xml file are skipped by MakePri.exe. These elements are either computed during indexing, or are specified in the MakePri.exe configuration file. Resource names, qualifiers, and values that are contained within the dump file are directly maintained in the new PRI file. The top-level resource map, however, is not maintained in the final PRI. Resource Maps are merged as part of the indexing.
This is an example of a valid string type resource from a dump file:
<NamedResource name="SampleString " index="96" uri="ms-resource://SampleApp/resources/SampleString ">
<Decision index="2">
<QualifierSet index="1">
<Qualifier name="Language" value="EN-US" priority="900" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
</Decision>
<Candidate type="String">
<QualifierSet index="1">
<Qualifier name="Language" value="EN-US" priority="900" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>A Sample String Value</Value>
</Candidate>
</NamedResource>
This is an example of a valid path type resource with two candidates from a dump file:
<NamedResource name="Sample.png" index="77" uri="ms-resource://SampleApp/Files/Images/Sample.png">
<Decision index="2">
<QualifierSet index="1">
<Qualifier name="Scale" value="180" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<QualifierSet index="2">
<Qualifier name="Scale" value="140" priority="500" scoreAsDefault="0.7" index="2"/>
</QualifierSet>
</Decision>
<Candidate type="Path">
<QualifierSet index="1">
<Qualifier name="Scale" value="180" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>Images\Sample.scale-180.png</Value>
</Candidate>
<Candidate type="Path">
<QualifierSet index="2">
<Qualifier name="Scale" value="140" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>Images\Sample.scale-140.png</Value>
</Candidate>
</NamedResource>
