Mario ontology network

The MARIO Ontology Network (MON) aims at providing MARIO robot with the means for creating, organising, querying and reasoning over a background knowledge base (e.g. to store/retrieve user’s personal information).
MARIO background knowledge consists of: lexical knowledge (e.g. natural language lexica and linguistic frames), domain knowledge (e.g. cga, personal sphere), environmental knowledge (e.g. physical locations and maps), sensor knowledge (e.g. RFID, life mesures), and metadata knowledge (e.g. entity tagging).
The MARIO Ontology Network (MON) is composed of different ontologies that cover different knowledge areas that are relevant to MARIO in order to make it a cognitive agent able to support older patient affected by dementia.
The knowledge areas were identified by analysing the use cases that emerged from the MARIO project.
These uses cases mainly describe actions and behaviours featuring the MARIO robots.
Nevertheless, they also provide us with detailed descriptions about the nature of the knowledge that the robot should deal with in order to perform and select actions and behaviours, respectively.
Currently, the MON consists of 12 knowledge areas and 36 modules.

Cultural heritage


ArCo is an initiative of the ICCD (Istituto Centrale per il Catalogo e la Documentazione) and the CNR (Italian National Research Council), as part of the project, for cultural heritage enhancement through the publication of LOD. ArCo aims at making available data from the Catalogo generale dei beni culturali following the paradigm of the Linked Data initiative, in an open format, in order to ensure accessibility to users and interoperability. The main activities of the project will include: the definition of a network of ontologies for representing the informations contained in the general catalogue, in relation to different types of cultural objects, taking into account the actual ICCD standards the publication of the data processed in the SiGeC (Sistema Generale del Catalogo, following the Linked Open Data principles, to populate the MiBACT SDL (semantic digital library). the building of a constant dialogue and a cooperation with private and public actors, who want to be early adopters. All releases of the project will be published on GitHub.

Here the first unstable release of ArCo: version 0.1 alpha.

Cultural Heritage

The project aims at identifying and providing technical solutions, based on standards of the Semantic Web, to enable the integration and rationalisation of MiBACT's data sources related to cultural heritage. To improve availability and reusability of the information assets owned by MiBACT, and to promote open government principles as well, the project started from the so-called DB Unico 2.0 registry, currently available as Open Data of level 3, by opening its content according to the design principles and recommendations of the Italian guidelines on "Semantic interoperability through Linked Open Data" and the W3C Linked Open Data best practices.


Cultural heritage ontology

The main activities of the project included

  • Definition of an OWL ontology for representing the information related to cultural institutes or sites (e.g., museums, historical archives, libraries, monuments, archaeological sites, etc.) and cultural events (e.g., exhibitions, seminars, conferences, etc.). The ontology aims at modelling cultural institutes or sites and all the data that can characterise them. Examples of data are: agents that act on a cultural institute or site, sites, contact points, the multimedia material describing the cultural institute or site, the services and any other information useful to the public in order to access the institute or site. Moreover, the ontology represents events that can take place in specific cultural institutes or sites, modelling all the data regarding possible tickets required to access to the event.
  • Automated extraction of the data from DB Unico 2.0 by means of D2R.
  • Production of the RDF dataset (and the related metadata) by following the Linked Open Data principles.




Conceived by the Directorate-General for Maritime Affairs and Fisheries (DG MARE) of the European Commission, the project focuses on the establishment of a single information system for fishery and aquaculture products marketed in the European Union. The information system, available as a fully operational multilingual prototype, aims at providing different stakeholders (consumers, producers, fishmongers, processors, importers, retailers, control authorities and other interested parties) with heterogeneous information related to commercial designations of fishery and aquaculture products put on the market in the EU Member States. MARE combines a solid taxonomic and nomenclatural backbone for aquatic species and their scientific names with commercial designations published by each Member State's national authorities in accordance with EU regulations. This core information is complemented with heterogeneous data that include, among the others, production methods, fishing gears, fishing areas, marketing standards, quality certification schemes, fishing opportunities and species distribution.


In the context of the MARE project, STLab has defined a modular ontology and produced a corresponding dataset for representing heterogeneous information about fishery and aquaculture products. Dealing with the complexity of the fishery domain and the heterogeneity of the available data sources requires the adoption of a well-designed, consolidated methodology, with the aim of obtaining open, interoperable and reusable models and data.

To favor semantic interoperability and reuse, the MARE ontology exploits well-established ontology design patterns and was designed following a modular approach. In particular, the information about aquatic species marketed in the European Union is structured in three interconnected modules, each focusing on a specific informational dimension or perspective. The identified ontology modules include:

  1. Mare Taxa, which focuses on taxonomic and nomenclatural data for aquatic organisms, such as taxonomic names, synonyms, taxonomic ranks, hierarchical classification, etc.
  2. Mare, which focuses on data related to commercial and legal requirements, such as commercial designations in the EU Member States, production methods and fishing gears, marketing standards, fishing quotas, nutrition facts, etc.
  3. Mare Geo, which focuses on geographical data related to aquatic organisms, such as major fishing areas, species distribution maps, etc.

Following the Semantic Web standars and principles, MARE ontology modules and core concepts are aligned to existing external authoritative ontologies available on the Web, so as to enable semantic interoperability and data linking.

The FOOD (FOod in Open Data) project defines and makes available standardization models and reference ontologies for representing food quality certification schemes, in accordance with product specifications defined by the Italian Ministry of Agricultural, Food and Forestry Policies. FOOD focuses on the semantic representation of the information and prodution rules set out in the product specifications for agri-food products and their quality designations, including Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) schemes.


Food ontology

The design of reference ontologies and the production of open data have been the core activities in the FOOD project. Specifications for agri-food products and their quality designations have driven the definition of a set of OWL ontologies. The ontologies model both quality certification schemes (PDO and PGI) and product categories (e.g., wine, cheese, meat, fruit, etc...) belonging to these certification schemes. Automated and manual data extraction techniques were used to produce RDF datasets (and related metadata) for the defined ontologies, in accordance with the Linked Open Data paradigm. The designed ontologies rely on design patterns and reuse existing ontologies (e.g., AGROVOC); the corresponding datasets are linked to and aligned with datasets available in the Web of Data (e.g., DBpedia, SPCData).

Public Administration


Enhancing Open Data to Linked Open Data is challenging especially in case of Big Data. Providing an effective breakthrough to this challenge in the context of data coming from the Italian Public Administration (PA) is the objective of this project, which is co-founded by Italian Digital Transformation Team ( and STLab. STLab is contributing to the project by designing a modular and high-scalable Ontology Network called OntoPiA.

Core ontology

The conference-ontology is a new self-contained ontology for modelleing knowledge about conferences. The conference-ontology adopts best ontology design practices (e.g., Ontology Design Patterns, ontology reuse and interlinking) and guarantees interoperability with SWC ontology and all other pertinent vocabularies.

Alignments to other scholarly vocabularies

This ontology provides alignments between the core ontology of scholarly data and other ontologies or vocabularies that model knowledge within the domain of scholarly publications.


Scholarlydata dataset is a refactoring of the Semantic Web Dog Food (SWDF), in an effort to keep the dataset growing in good health. We use a novel data model, the conference-ontology, which improves the Semantic Web Conference Ontology, adopting best ontology design practices.

All the current data can be accessed in different formats (i.e., HTML, RDF/XML, Turtle, N-TRIPLES, and JSON-LD) via URI dereferencing, queried via SPARQL or downloaded as single RDF dumps for each conference and workshop.
