Linked open data for halal food products

The life of a Muslim cannot be separated from the concept of halal in his daily life, especially in food. Indonesia is a country that its major population is Muslim. In Indonesia, Institute For Foods, Drugs, And Cosmetics Indonesian Council Of Ulama as known as LPPOM MUI is an organisation that provides halal food product information. However, lack of information is presented on LPPOM MUI site. Therefore, LODHalal, a Linked Open Data system for halal products is proposed. We introduce a halal vocabulary which extends two food vocabularies. Then, collected data from LPPOM MUI, E-Number, Open Food Facts are transformed to RDF. Also, the RDF data are connected to DBpedia, PubChem and Mesh. We develop a web application and an Android application which provides recommendations on the halal and nutritional status of a food product.
