Open Laptop


PDFKeeper began as an idea to solve a personal document storage issue. With both digital and paper documents stored in many places, it was becoming a challenge to locate documents quickly, especially at tax time. What proved to be an even bigger challenge was locating a free solution that could store PDF documents in a free, full-text search ready, relational database that could be accessed by anyone on the local area network. In addition, I had a requirement to store notes in the database with the PDF document that would also be searchable.

In early 2009, after being unsuccessful in locating a solution, I started building PDFKeeper, an open-source application that would use a free, full-text search ready, relational database for PDF document and notes storage, targeted at the Small Office Home Office and Small Business community. To develop the application quickly, I decided to build it with Open Object REXX, a scripting language with GUI support that I was very familiar with from my OS/2 days. As for the database, I chose to use Oracle® Database XE since it was free and was capable of indexing PDF documents; but, it was my plan to expand database compatibility to other platforms over time.

Here are some development milestones by year: (for more details, please see the Changelog)

Store and manage PDF documents in a single-user or compatible, multi-user (on-prem or cloud) database where they’re indexed to provide full-text search functionality.

Upload PDF documents individually or in bulk. In addition, Upload Profile folders can be setup to allow for integration and automation.

Apply a category/tax year to selected documents and when PDF documents are uploaded.

Set the flag state on a selected document and when PDF documents are uploaded to mark for follow-up.

Add notes to a selected document that can include the date, time, and user account name. All notes can be edited and are indexed by the database.

Find documents by Search Term, Selections (Author/Subject/Category/Tax Year), or Date Added. In addition, flagged documents or all documents can be listed.

With PDFKeeper, the following functions can be performed on a selected document: PDF viewing with the bundled or default viewer; PDF bursting; flag document state management; notes viewing and editing; keywords, PDF preview, PDF text, and search term snippets (when applicable) are also displayed for viewing.

Export selected PDF documents with their category, tax year, notes, and flag state from the database for easy importing.
