Older MS Office files all had the same four bytes, which presented complications, especially since so many files were in one of the four Office formats. Once you have that, you can quickly parse the file. Many file types can be identified by an initial set of four bytes. They publish standards for most of their file types these days, particularly the newer ones. Things have changed a lot over the years Microsoft is actually at the forefront for publishing standards. There aren’t a lot of standards available for how files are structured what exists may be incomplete or outdated. If you are lucky to get a plaintext file, then that’s an easy one. The first step to locating or extracting text from a file is finding out what format the file is in. Lots of files and formats pass through during tests and they need to come through clean. Today, we’ve expanded those tests and made error detection much more strict.

With the conversion to C++, we wrote a lot of new tests in order to exercise as much code on all platforms. Some of the solution to that problem is just writing everything as generically as possible without special code for each platform. Ultimately, the goal is to have the software run exactly the same on all 27 platforms. We make sure to abstract this away so no one needs to figure out the originating chipset before processing a file. When you’re reading from a file, you need to know what chipset produced it, otherwise you could read things backwards. SPARC chips historically used in Solaris machines used big-endian storage, where the most significant byte was stored first. All Intel and ARM chips use little-endian, where the least significant byte is stored first. Different CPUs process bytes in different orders, called byte endianness.

Each compiler makes different assumptions of how to implement C++ code, so we use multiple compilers to see what those assumptions are.Ĭomplicating things was that we not only had to consider operating systems, but CPUs as well.

The other 20% was new OS abstractions, primarily to support the Windows API functions we lose on other platforms and the various quirks of each platform.

We were able to port about 80% of the code from Pascal.

We considered writing it in C, but we would have had to invent a lot of the boilerplate that C++ gave us for free. That wasn’t going to work for us, as we wanted to support big backend processing servers like Solaris and HP-UX.

At the time, Pascal only supported Windows, and while it now supports Mac and Linux, it was and still is a niche language. When we rewrote our software, one of the key factors was platform support. Since then, we’ve learned a lot about content processing at scale and how to make it work on any platform. Identifying that Pascal was not going to meet our needs we pivoted our engineers to rebuild the app in C++ over the next year for about half a dozen computing platforms. Our customers noticed our strength in text extraction and wanted that as something they could integrate or embed in their software and across multiple platforms. This led us to realize that the sum of the parts was greater than the whole getting text out of files and delivering the exact location is harder than it seems and relevant to applications other than search. Eventually, other companies, such as Microsoft and Google, started providing desktop search applications for free, and it’s tough to compete with free. The application was built in Pascal for MS-DOS and provided mainframe-level search on PCs. We started as a company that sold desktop search software called ISYS. We give you one dependency, one point of contact if something goes wrong, and one library to deploy instead of dozens. One library for 550 formats may seem like overkill, but imagine stringing together dozens of open source libraries, testing each of these libraries each time a new release hits the wild. These are Document Filters, and any software that interacts with documents will need Document Filters. The challenge is even greater when it’s time sensitive, for example if you have to scan all outgoing emails for personally identifiable information (PII) leakages, or you have to give patients a single file that contains all of their disclosure agreements, scanned documents, and MRI/X-ray/test reports, regardless of the original file format.Īt Hyland we produce a document processing toolkit that independent software vendors can implement to identify files, extract text, render file content, convert formats, and annotate documents in over 550 formats. The formats, versions, and platforms that generated them could be wildly different. Imagine you’re a recruiter searching resumes for keywords or a paralegal looking for names in thousands of pages of discovery documents. We take for granted document processing on an individual scale: double-click the file (or use a simple command-line phrase) and the contents of the file display.
