Thot APIs

Central to data sharing, (Application Programming interfaces (APIs) are entry points developed by projects to make accessible their data to external parties. As for Project Thot, APIs have been built in order to make Thot thesauri and concepts very accessible and easy to use. For instance, pointing to a specific URL will retrieve the full set of concepts of a thesaurus as sorted data, or will display preferred label or date ranges attached to a concept, as explained below:

Available services and how to access them

Service Data type URL structure after http://thot.philo.ulg.ac.be/ Example
Get skos:Concept RDF api/rdf/concept/ + thot-concept http://thot.philo.ulg.ac.be/api/rdf/concept/thot-23
Get skos:prefLabel txt api/txt/preflabel/ + thot-concept/ + lang http://thot.philo.ulg.ac.be/api/txt/preflabel/thot-23/fr will return "Copte fayoumique"
Get date range (date thesaurus only) txt api/txt/get-dateRange/ + thot-concept http://thot.philo.ulg.ac.be/api/txt/get-dateRange/thot-465 will return "450-400 BC"
Get start of date range txt api/txt/get-dateStart/ + thot-concept http://thot.philo.ulg.ac.be/api/txt/get-dateStart/thot-465 will return "-450"
Get end of date range txt api/txt/get-dateEnd/ + thot-concept http://thot.philo.ulg.ac.be/api/txt/get-dateEnd/thot-465 will return "-400"
Get a specific thesaurus in English JSon api/json/thesaurus/ + thesaurus name http://thot.philo.ulg.ac.be/api/json/thesaurus/scripts
Get a specific thesaurus in a specific JSon api/json/get-thesaurus/ + thesaurus name + "/" + ISO language code http://thot.philo.ulg.ac.be/api/json/get-thesaurus/scripts/fr (see use case below)

Available data types and languages

The current data type are as follows:

  • JSon
  • Plain text

Current languages are English (en), French (fr), German (de). To get the xml value attached to a concept (see here), use 'xml' as language name.

Retrieve and display data from Thot

Load data with Ajax and display it in your HTML page

Using ajax, you can retrieve values attached to a Thot concept and diplay them in your webpage. For instance, let's suppose you have a database of funeral texts from the New Kingdom. One of your record is dated to Amenhotep II reign. The only piece of information you have to store is that this record is related to thot-374, the concept that corresponds to that king. Using the API, you will be able to automatically display name (the German form in the example below), a date range and mumerical values corresponding to this range

  • Reign:
  • Date range:
  • Earliest date:
  • Lastest date:


<li>Reign: <span id="kingName" /> </li>
<li>Date range: <span id="dateRange" /></li>
<li>Earliest date: <span id="dateStart"/></li>
<li>Lastest date: <span id="dateEnd"/></li>

JScript and Ajax function

<script type="text/javascript">
$(document).ready(function (){
        method: "GET",
        dataType: "text",
        success:function(data) {
    $.ajax({ method: "GET",
        dataType: "text",
        success:function(data) {
    $.ajax({ method: "GET",
        dataType: "text",
        success:function(data) {
        $.ajax({ method: "GET",
        dataType: "text",
        success:function(data) {

Thot thesauri in JSon

Thot thesauri are available as JSon data through the following requests (http://thot.philo.ulg.ac.be/api/json/ + thesaurus shortname):

Example of use of Thot thesauri in a form

Thot thesaurus can be displayed as a tree in a form, for instance by implementing Fancytree JQuery library (https://github.com/mar10/fancytree).

Select a value

<form action="" method="POST">
