Urgent PHP Developer for Intranet Site

I'm urgently seeking a skilled PHP developer to modify an intranet site "owl". Owl is a multi user document repository or knowledge based system. Users are able to capture documents and assign attributes to them when the document is uploaded into the Owl system. Other users are then able to locate the documents either by using the hierarchy folder structure or by using the built in search facility. A document can be any type of electronic document or file that the user can access from their computer. Typically theses documents could be a word processing file, spreadsheet, or PDF files. But Owl is not just limited to common office file types you can capture most graphic file types, and display them within the system, audio and video or executable program files. In fact Owl is only limited by your [login to view URL] documents have been captured by the owl system users have numerous options: Ability to e-mail documents directly from Owl Users can monitor documents or folders for updates and receive notification by e-mail A Version Control System (VCS) can be used to track changes to documents, keep copies of old documents and provide a change log. Users can add comments to individual documents All these facilities are easily available through the use of an Internet Browser. File Browser The browser is the main method, which you will use to navigate the hierarchical folder structure and to find and use documents that have been captured into the system. You can carry out certain actions on folders and documents such as sorting the displayed order, viewing or downloading the document, or e-mailing the document to some one. Folder Structure Documents that are uploaded into the Owl system are stored in folders and each folder can have a series of sub folders. This type of structure is known as a hierarchical structure and is typically used for the storage and organization of files on your computer's hard drive. In Owl, the start point of the hierarchy (or root) is known as the documents folder. The folder structure allows a convenient way to group documents in a meaningful fashion. For instance, you may wish to capture all your technical documents for a number of products. You could create a folder named technical documents and then a series of sub folders inside technical documents of each product. For this to work properly, you must chose sensible and descriptive folder names that provide the user with a reasonable description and meaning. Title Bar Browsing Documents Checkbox to check or uncheck documents or folders for bulk operation Status Anyone of the following icons can be displayed: * The document has been indexed, i.e. it is possible to search within this document The document has been added since your last visit The document has been updated since your last visit The document has a user comment doc_number The specific number of the document. title The title of the document or the folder. ver The version of the document or the folder.
