LexO-server: REST services for Linguistic Linked Data

LexO-server is a software backend providing REST services for building and managing lexical and terminological resources in the context of the Semantic Web. It relies on the OntoLex-Lemon model.

Services can be consulted here via a Swagger interface

Features

• Targeted for web apps oriented at different lexicographic-based tasks, such as editing, linking, data visualization, dictionary making, linguistic annotation
• Lexical level implemented by the OntoLex-Lemon model
• Conceptual level implemented by the SKOS model
• Integrated user authentication addressed by KeyCloak (forthcoming)
• Possibility to manage bibliographical items with Zotero (forthcoming)
• Integration with remote SPARQL endpoints (forthcoming)
• Export data as Linked Data (RDF/XML, Turtle, N3, NQuads)

Tech

LexO-server uses the following technology to work properly:

• Java 15 or later
• Apache Tomcat 9 or later
• GraphDB Free - Semantic Graph Database, compliant with W3C Standards.
• MySql - Open-source relational database management system (RDBMS)

Installation

1. Install GraphDB.
2. Create an empty GraphDB repository with default values.
3. Download the project.
4. Edit the pom.xml file, as follows:

    <profile>
        <id>release</id>
        <properties>
            <db.jdbcUrl>leave_empty</db.jdbcUrl>
            <db.user>leave_empty</db.user>
            <db.password>leave_empty</db.password>
            <graphdb.url>$graphdb_intallation_url$</graphdb.url>
            <graphdb.repository>$repo_name$</graphdb.repository>
            <graphdb.poolSize>5</graphdb.poolSize>
        </properties>
    </profile>

where graphdb_intallation_url is the url of your GraphDB installation (typically on port 7200), and repo_name is the name of the repository to connect to.

5. Compile the project with Maven.
6. Run the build.
7. Open the browser at http://localhost:8080/LexO-backend/, and the swagger sholud appear.
