The SPARQL Micro-Service architecture is meant to allow the combination of Linked Data with data from Web APIs. It enables querying non-RDF Web APIs with SPARQL, and allows on-the-fly assigning dereferenceable URIs to Web API resources that do not have a URI in the first place. This project is a PHP implementation for JSON-based Web APIs. It...

Abstract of a poster presented at the TDWG 2018 conference on Biodiversity Information Standards.

Morph-xR2RML is an implementation of the xR2RML mapping language (https://www.i3s.unice.fr/~fmichel/xr2rml_specification_v5.1.html) that enables the description of mappings from relational or non relational databases to RDF. It comes with connectors for relational databases (MySQL, PostgreSQL, MonetDB) and the MongoDB NoSQL database.

VAPOR, the Vo Administration and operations PORtal, is a generic tool to assist managers and support teams of grid user communities perform daily administrative and operational tasks. Targeted communities may typically be of small to medium size, have no or few dedicated IT support, have fragmented user groups, and may possibly make an...

VAPOR, the Vo Administration and operations PORtal, intends to help small to medium-size grid user communities to perform common VO administration and operational tasks, at a reduced human cost. Such communities may typically have no or few dedicated IT support, have fragmented user groups, and may ...

To a great extent, the success of the Web of Data depends on the ability to reach out legacy data locked in silos inaccessible from the web. In the last 15 years, various works have tackled the problem of exposing various structured data in the Resource Description Format (RDF). Meanwhile, the overwhelming success of NoSQL databases has made...

How to publish our scientific datasets on the web and make them interoperable, using technologies from the Semantic Web.This presentation shortly reminds the needs and incentives for publishing scientific datasets on the web, with a focus on both the metadata and data content.It first goes through a presentation of the Web of Data and the...

Web APIs have become a de-facto standard to enable HTTP-based access to machine-processable data. In this talk, I will present the SPARQL micro-service architecture, a lightweight approach that bridges web APIs and RDF knowledge graphs by making it possible to enforce a uniform data model over multiple sources, while using SPARQL as a unique...

Over the last 70 years, we, humans, have created an economic market where attention is being captured and turned into money thanks to advertising. During the last two decades, leveraging research in psychology, sociology, neuroscience and other domains, Web platforms have brought the process of capturing attention to an unprecedented scale....

In recent years, the growing need for easily accessible highquality educational resources, supported by the advances in AI and Web technologies, has stimulated the development of increasingly intelligent learning environments. One of the main requirements of these smart tutoring systems is the capacity to trace the knowledge acquired by users...

Production operation of large distributed computing infrastructures (DCI) still requires a lot of human intervention to reach acceptable quality of service. This may be achievable for scientific communities with solid IT support, but it remains a show-stopper for others. Some application execution environments are used to hide runtime technical...

Une des missions du Muséum national d'Histoire naturelle (MNHN) est d'établir une synthèse de la biodiversité et du patrimoine naturel français. Dans ce contexte, il est en charge de l'élaboration du référentiel taxonomique pour la faune, la flore et la fonge, TAXREF. Ce référentiel unique liste et organise les noms scientifiques de l'ensemble...

Operating a large production-level distributed computing infrastructures today still requires a costly human intervention to reach acceptable quality of service. This cost may be acceptable for scientific communities with solid IT support, but it often remains a show-stopper for others. The Life-Science Grid Community (LSGC) gathers five...

We present the WASABI 1 Song Corpus, a large corpus of songs enriched with metadata extracted from music databases on the Web, and resulting from the processing of song lyrics and from audio analysis. More specifically, given that lyrics encode an important part of the semantics of a song, we focus here on the description of the methods we...

Abstract of a demonstration of the SPARQL micro-services architecture to integrate various biodiversity-related linked data datasets and Web APIs.

Relational databases scattered over the web are generally opaque to regular web crawling tools. To address this concern, many RDB-to-RDF approaches have been proposed over the last years. In this paper, we propose a detailed review of seventeen RDB-to-RDF initiatives, considering end-to-end projects that delivered operational tools. The...
