Hi, My name is Yi Zhu. I am a MSc student of EPCC, majoring in High Performance Computing. I am here because my final project is about DFDL (I am sorry for that as the project has just begun, what exactly will be implemented has not been decided), and I believe this is a interesting, challenging and promising field. However, I am a real beginer in DFDL, so I need all your help. Thanks ever so much! Regards, Yi
Do you need help selecting or defining your DFDL project Yi? Is it a 3 month project? With programming? Do you have to write a thesis? A paper? How many pages roughly?

Hi Susan, Thank you very much. Yes, it is a 3 month project with programming and we have to submit a dissertation with roughly 15,000 words at the end of August. My supervisor gave me some advices about what to do: implementing a basic parser for a subset of the DFDL specification using Java, maybe via SAX and DOM respectively, and then benchmarking different performances. However, I have not decided which subset of DFDL I should work on because I have no idea among what I can choose. In addition, I haven't had a detailed view about what the DFDL can do and how it does it, I mean the annotation syntax for different problems, although I know it can define all kinds of data using the combination of the XML schema and DFDL annotations. Could you give me some advices? Cheers, Yi On Tue, 26 Apr 2005, Susan Malaika wrote:

How about considering the subset of DFDL that is useful for describing JPEG metadata or some other binary format that may be of interest in EPCC? You could build some software that uses DFDL annotations as the basis for processing JPEG metadata? You could make an assessment of your findings in your dissertation and give feedback to the DFDL working group .... First steps would be to look at JPEG metadata (if that seems suitable) and look at the latest DFDL documents posted on the DFDL Website.

Hi all, After discussing with my supervisors, I decided to take Susan's suggestion (thank you ever so much Susan) and describe JPEG image files using the subset of DFDL in my MSc projcet. Now I have some questions, could you help me? 1. Do you think there are any particular JPEG test images I can use? I tried to find on the Internet, but I can't probably because of the copyright. 2. I know that JPEG files have a clear structure (marker segments), but different images also have some segments with different length (coding segments). How can I use DFDL to describe these various segments? 3. I have downloaded the example from the working group website, but are there any other examples based on real problems? I mean, for instance, an example of describing a flat binary data file, or an example of describing a database. And are there any examples of DFDL parsers or DFDL applications? Thank you very much!
