A wiki can be an effective solution for maintaining and updating numerous versions of a document like a PDF, especially considering that wikis are designed to manage collaborative content creation and version control. Here are some factors to consider when using a wiki for this purpose:
Version Control: Wikis inherently support version control, allowing you to keep track of changes made to each document and revert to previous versions if necessary. This feature is beneficial when managing multiple versions of a document.
Collaboration: Wikis allow multiple users to collaborate on documents in real-time, which is ideal for environments where many people need to contribute to or update the documents.
Access Control: You can set permissions to control who can view or edit each document version, ensuring that sensitive versions are only accessible to authorized personnel.
Organization and Searchability: Given the large number of versions, organizing them systematically within a wiki using categories, tags, or hyperlinks can make it easier to navigate and find specific document versions.
File Management Challenges: While wikis handle text and images well, managing binary files like PDFs can be less straightforward. It’s often beneficial to store PDFs externally and link to them from the wiki to avoid performance issues and maintain file integrity.
Integration with Other Tools: Consider whether your wiki platform offers integrations with document management tools or revision platforms that can streamline the process of handling PDF documents.

In summary, while a wiki offers several advantages for maintaining multiple document versions, it is important to address file management challenges and ensure that your chosen platform supports the specific needs of managing PDF documents.
