Semantic Treehouse has a new front-end! At the end of November we rolled out the new front-end version 3 for all Semantic Treehouse environments. Although it is still a beta version (v3.0.0-beta), the new front-end fully covers all views from the previous environment and has been extensively tested so that using it is an immediate improvement.

Besides a new look and feel, many more improvements have been made in the new Semantic Treehouse front-end:

This blog post will address how Semantic Treehouse supported the needs of a data sharing community in creating a new standard. Among the dedicated users of Semantic Treehouse is the SETU foundation, the organization for data standardization of the flexible staffing industry in the Netherlands. Recently, SETU developed the Planning and Scheduling standard, enabling seamless data exchange of planning information between staffing suppliers back-office software, planning tools, and interconnecting planning tools.

For this Planning and Schedulling standard, there was a desire to repurpose HR Open specification whenever feasible. This involved creating multiple message models by carefully selecting elements from the HR Open Model in JSON Schema and incorporating SETU specific additions and restrictions. Furthermore, SETU's goal was also to create schemas in both JSON and XML formats, along with Open API specifications for seamless implementation and validation. The following text highlights how Semantic Treehouse supported the SETU foundation in reaching their goals.

Domain-specific vocabularies are crucial for accurate and consistent data interpretation by different individuals and systems. These vocabularies provide a shared conceptualization of knowledge within a particular domain. We observe the emergence of these vocabularies in diverse formats such as Smart Data Models, HR Open and Open Trip Model, which express their vocabularies in JSON or XML schemas.

Thanks to our friends at IDSA, I had the opportunity to talk about semantic interoperability in data spaces. Here's the official description of the event:

On the 15th of March I had the opportunity to present the concept of a Vocabulary Hub in the "Towards data spaces" track of the ENDORSE conference 2023.

You can downloaded the Presentation slides and read our position on the Vocabulary Hub.

Op 3 november organiseerde TNO een Semantic Treehouse gebruikersmiddag in Utrecht. Aan alle deelnemers onze hartelijke dank voor jullie aanwezigheid en waardevolle inbreng!

Terugblik​

Het doel van deze middag was tweeledig. TNO wilde samen met klanten en collega standaardisatie-experts:

1. Kennis en ervaringen delen over het huidige en gewenste gebruik van Semantic Treehouse in verschillende branches
2. Samen de toekomstige ontwikkelroadmap van Semantic Treehouse vormgeven

We are very proud that today, during the 'Semantic Treehouse gebruikersmiddag' in Utrecht, we officially launched the new Semantic Treehouse website. By launching this new website, a long-cherished wish to work towards an own, unique look-and-feel has been fulfilled.

Today we had the opportunity to present our applied research activities in the field of semantic interoperability in data spaces to the PLDN community. PLDN is the community of linked data experts in the Netherlands. In my presentation I positioned the importance of semantics, shared ontologies and a Vocabulary Hub in realizing semantic interopability in a data space.

Position paper​

To read more about the topic of semantic interoperability in data space, please take a look at our position paper The Vocabulary Hub to configure data space connectors

Our colleague Wouter van den Berg (TNO) presented our position paper The Vocabulary Hub to configure data space connectors at the workshop Data Space & Semantic Interoperability in Vienna.

In this position paper we propose a wizard-like approach for data space connector configuration, where data consumers and data providers are guided through a sequence of steps to generate the specifications of their data space connectors, based on the shared vocabularies in the vocabulary hub. We illustrate this with our own implementation of a vocabulary hub, called Semantic Treehouse.

Op 17 maart 2011 had ik samen met collega's mijn eerste SETU-overleg. Op dat moment ben ik twee maanden werkzaam bij TNO, net afgestudeerd en een groentje als het gaat over data-delen. Aangenomen als junior adviseur IT-governance, was mijn betrokkenheid bij het SETU-project bedoeld als een klein uitstapje waar ik mijn adviesvaardigheden kon ontwikkelen. Nietsvermoedend dat het onderwerp data-delen en data-standaarden de rode draad en mijn expertise zouden worden in de ruim 10 jaar die volgden.
