The Ajax XML Encoder (AXE), developed by Doug Reside at the Maryland Institute for Technology in the Humanities, allows users with limited technical knowledge to add metadata to text, image, video, and audio files. Users can collaboratively tag a text in TEI, associate XML with time stamps in video or audio files, and mark off regions of an image to be linked to external metadata. AXE also facilitates collaboration in the digital humanities by permitting multiple scholars to work on the same document or archive at the same time from various locations, and will track all work so that variant versions can be collated and all versions can be archived. The Ajax XML encoder, with its intuitive Web-based interface, will come as a breath of fresh air to those who have previously been frustrated by text-centric tagging tools which require an expert knowledge of mark-up languages.
