>That is something I have also thought of as well, the ability to have user-defined fields associated with parts. I've thought of creating an application to parse these fields after a ULP export. The application would make http requests to retrieve price/quantity information from various suppliers, and drop the results into an excel spreadsheet for analysis. User defined fields is a most-requested feature for Eagle, and I am sure that the developers are aware it is wanted. It would be great if vendors could respond to price requests in some standardized way, however I don't imagine that is a reality today. The best one could do is to keep one's own database, which would swiftly go out of date. Or possibly form the app around one supplier. If Digikey's website could respond in some intelligent way to a Digikey part number, then pricing info could be found, for one supplier at least. Such halfway solutions would prove frustrating, I believe. Specs, however, don't change as fast as pricing. A small database of specifications, such as low leakage capacitors and so on, might be useful to add to a BOM. --Lawrence --- Outgoing mail is certified Virus Free.
