Look for literals in an RDF graph and substitute them with URIs from controlled vocabularies. Built with Gradle and Apache Jena.

It uses the vocabulary filenames for grouping them in families. For example, city-italy.ttl and city-france.ttl are part of the family city.

The library needs in input:

• a folder containing vocabularies
• for a full graph replacement, a configuration in csv that declares the property to match, the relative vocabulary family, an if it should eventually check for the singular version of the label. Example:

http://data.doremus.org/ontology#U2_foresees_use_of_medium_of_performance,mop,singular
http://data.doremus.org/ontology#U11_has_key,key,

Given as input:

ns:myMusicWork mus:U11_has_key [
          a mus:M4_Key ;
          rdfs:label "Ré majeur"@fr ] ;
   mus:U2_foresees_use_of_medium_of_performance "mezzosoprano" .

... this produces as output:

ns:myMusicWork mus:U11_has_key <http://data.doremus.org/vocabulary/key/d> ;
   mus:U2_foresees_use_of_medium_of_performance  <http://data.doremus.org/vocabulary/iaml/mop/vms> .

• Vocabulary syntax supported:
  • SKOS
  • MODS
• Support for families of vocabularies
• Replace literals that match the given label
• Replace objects that have a rdfs:label or ecrm:P1_is_identified_by which match the given label
• Strict mode: match both label and language
• Normalise the labels by removing punctuation, decoding to ASCII, using lowercase
• Search also for the singular version of the word with Stanford CoreNLP
• Support for RDF Dataset:
  • replace content at the default graph level
  • replace content at a given named graph level
• Supported textual syntax for RDF (serialization):
  • RDF Turtle (.ttl)
  • TriG (.trig)

Dependencies:

• Build tool: Gradle 7+
• See the dependencies section in the build.gradle file for project dependencies.

1. Add it as dependency. E.g. in build.gradle:

dependencies {
   compile 'com.github.DOREMUS-ANR:string2vocabulary:0.7'
}

2. Import and init in your Java class

import org.doremus.string2vocabulary.VocabularyManager;

// ...

// print full logs
VocabularyManager.setVerbose(true);

// set the folder where to find vocabuaries
VocabularyManager.setVocabularyFolder("/location/to/vocabularyFolder");
// set the folder where to find the config csv
VocabularyManager.init("/location/to/property2family.csv");
// set the language to be used for singularising the words
VocabularyManager.setLang("fr");

3. Use it :)

// Search for a term in a given family
// this performs a normal full search and one in strict mode
VocabularyManager.searchInCategory("violin", "en", "mop");
// --> http://www.mimo-db.eu/InstrumentsKeywords/3573

// or
// Search for a term in a given vocabulary
VocabularyManager.getVocabulary("mop-iaml").findConcept("violin", false);
// --> http://data.doremus.org/vocabulary/iaml/mop/svl
// strict mode
VocabularyManager.getVocabulary("mop-iaml").findConcept("violin@it", true);
// --> null

// or
// Get the URI by code (what is written after the namespace)
VocabularyManager.getVocabulary("key").getConcept("dm");
// --> http://data.doremus.org/vocabulary/key/dm

// or
// Full graph replacement
// search and substitute in the whole Jena Model
// (following the csv configuration)
VocabularyManager.string2uri(model)

See the test folder for another example of usage.

Run the library from CLI with gradle run:

# Canonical form
gradle run -Pmap="/location/to/property2family.csv" \
  -Pinput="/location/to/input.ttl" \
  -Pvocabularies="/location/to/vocabularyFolder"

Available CLI parameters:

Default gradle run behavior rely on project properties set in the gradle.properties file. See the following links for details about properties in Gradle:

• Passing Command Line Arguments in Gradle
• Gradle project properties best practices
• Configuring Gradle with "gradle.properties"

CLI examples with provided test files:

# Example: Turtle syntax
gradle run -Pmap="src/test/resources/property2family.csv" \
  -Pinput="src/test/resources/input.ttl" \
  -Pvocabularies="src/test/resources/vocabulary"

# Example: TriG syntax, replace at the default graph level
gradle run -Pmap="src/test/resources/property2family.csv" \
  -Pinput="src/test/resources/input.trig" \
  -Poutput="src/test/resources/output.trig" \
  -Pvocabularies="src/test/resources/vocabulary"

# Example: TriG syntax, replace at the default graph level (alternative)
gradle run -Pmap="src/test/resources/property2family.csv" \
  -Pinput="src/test/resources/input.trig" \
  -Poutput="src/test/resources/output.trig" \
  -Pvocabularies="src/test/resources/vocabulary" \
  -Pgraph=""

# Example: TriG syntax, replace at a given named graph level
gradle run -Pmap="src/test/resources/property2family.csv" \
  -Pinput="src/test/resources/input.trig" \
  -Poutput="src/test/resources/output.trig" \
  -Pvocabularies="src/test/resources/vocabulary" \
  -Pgraph="http://example.org/graph/object/"
