An article may contain references that change over time. Maintenance should check whether the change changes the meaning of the explanation, in addition to the operation of the link. A source that can be reached may have been updated and no longer support the same claim in the same way.
I propose to distinguish minor corrections and revisions of the content. The text must maintain a degree of certainty consistent with the verifications available. Technical or regulatory information requires relevant sources and up-to-date reading, avoiding retaining conclusions only because they were present in the first version.
In a hypothetical example, an official guide modifies the path described for a service. The article may require a review of the instructions and the update date. Changing only the link can leave the reader with a process that is now different from the one available.
The management should keep the author and the status of the published content recognizable. Periodic verification is useful when following the importance and variability of references. Maintenance retains the value of the article by making consistent what the text explains with the information actually available at the time of consultation.
