@Superkalle If all goes well I should have a basic prototype pieced together in the next few days, hopefully that will give you an idea of what it is I am hoping to do. But simply put, I'm attempting to build a page that allows an anonymous user to upload a LXF, or LXFML file and get a Wanted List XML file in return.
Most of the problems you mentioned I have considered, but I haven't devised a good working solution for any of them just yet. As for the maintenance, I should be able to automate most of it, except for possibly the updates to LDD.
Maybe I'll just focus on these four questions for now:
Is the peeron color list actively maintained?
The Bricklink Part and Color Code download contains nearly 22,000 parts. Is this a complete list of parts available in their database?
Do you know of a simple way to obtain alternate item numbers from Bricklink in bulk? I'd rather not resort to scraping their entire site.
I have downloaded LDD manager but as I am on a Mac I can't run it. Is the mdb file something that anybody could open if they had MS Access?
And finally, I fear I may be at risk of hijacking this thread. Would this topic be better suited elsewhere?
Thanks for the insight.
