Updating with CFIHOS Entities – Scheduled Downtime

20 May 2025

On Thursday, May 30, we’ll be performing an update to PCA Library Services that will cause temporary downtime. During this downtime, we’ll be making some important updates — including the addition of CFIHOS Entities to our CFIHOS 2.0 RDL and the broader CFIHOS+ functionality.

The work is scheduled to begin at 09:00 (CET) and is expected to last for approximately two hours. If the update takes longer than planned, we’ll keep you informed in this article.

Why are we adding CFIHOS Entities?

There are several reasons for this important update:

CFIHOS Entities are an essential part of the CFIHOS standard. With them, our CFIHOS representation will be more complete.
These entities cover commonly used concepts such as site, plant, area, and more — all of which are essential in engineering and operations.
Their addition allows us to retire the temporary CFIHOS 2.0 Meta Ontology, which was used as a placeholder. The new setup will be more accurate, self-explanatory, and easier to maintain.

This update makes our CFIHOS representation more complete, more transparent, and better aligned with the original standard.

Thanks for your patience while we make this improvement. If you have any questions, feel free to contact us at support@posccaesar.org.
