The objective of D2.9 is to provide best practices and guidelines for the utilization, exploitation, maintenance, and further development of the tools, methodologies, and infrastructure resulting from the efforts of WP2. This guidance is contextualized within the scope of the overall project. This white paper offers an overview of relevant practical and theoretical aspects related to (1) the TRO and (2) the MRO/Bridge-Concepts, presented in D2.7 and D2.8, respectively. As core contributions, D2.9 also includes a detailed discussion of (3) the OCES Framework (OWL), and (4) a list of technical principles endorsed by OntoCommons. This list serves as both effective recommendations that consider the current landscape and state-of-the-art literature and as requirements for stakeholders.
