What indicates that files have reached the publishing stage in Relativity?

The indication that files have reached the publishing stage in Relativity is primarily shown by the completion of deduplication. Deduplication is the process of identifying and removing duplicate files from the dataset. By ensuring that only unique files are retained, the publishing process can proceed with a polished and refined set of documents.

When deduplication is complete, it suggests that the dataset has been prepared for further steps, such as publishing, where the focus shifts from cleaning and organizing files to distributing them for review or production. Therefore, recognizing that deduplication is finalized effectively signifies that the dataset is at a mature phase of preparation, ready for publication in the workflow.

In terms of the other options, while having all files clean, identifying a master document, or completing document ID creation are important processes, they do not solely indicate that files have progressed specifically to the publishing stage. These aspects may contribute to the overall readiness of files but do not directly correlate with the critical point of readiness for publishing as deduplication does.
