I mentioned previously that it is possible, and in fact quite easy, to install Wikipedia locally which has several advantages but also one disadvantage.
Advantages should be clear: you do not need an Internet connection to access Wikipedia contents, you can distribute the solution to as many computers as you want and you can make it available in a local area network. Look ups should be faster as everything's already available locally.
The only disadvantage that I can think of is that some articles may have been updated in the meantime which means that you don't get access to those updates until you download the package files again.
The English database file has a size of more than 11 Gigabytes - packed that is - and it can take some time to download it depending on your Internet connection.
I did use a download manager to make sure that the download does not get interrupted and I would have to start over again. Here is the list of files that you do need, I walk you through the installation afterwards:
I suggest you start by downloading the files needed. The Wikipedia database download will naturally take longer than the other two downloads which is excellent for our purpose.
Once XAMPP has been downloaded install it. You are asked if you want to add services to your system during installation, this is not needed. Make sure you start the XAMPP control panel afterwards.
Keep this open and wait for the downloads to finish. Now unpack the file that contains the Wikipedia articles and wait for it to finish. The unpacked file has a size of more than 13 Gigabytes so make sure you have enough free hard drive space on that drive.
Now add the date of the release in the format YYYYMMDD to the file name. I added it at the end before the .xml.
Now run WikiIndex.exe and drag and drop the XML file in the program window. It starts indexing the database file which should take a while as well (5 minutes on my system). We are almost done now.
You need to locate the httpd.conf file in the XAMPP directory and add an entry to it. The file is located in xampp\apache\conf. Just open it with a normal text editor and add the following line at the end:
LoadModule WikiFilter_module "C:/Program Files/WikiFilter/WikiFilter.so"
Please replace the path to the WikiFilter.so file with the path on your system. You should also note that the file path uses "/" instead of the usual "\" to separate directories.
Start Apache using the XAMPP control panel and point your browser to the url http://localhost/wiki/. If everything went well, you should see Wikipedia pop up in your browser of choice.
