Hi, I'm looking for something to hold a cached version of a parsed domain model, typically from large HTML or CSV files on disk, parsed with XMLHTTPParser or NeoCSV. Occasionally also JSON and HTML from a web service. The files are frequently updated, so it should check for this at least on disk and reload before returning the cached model to the application. It's not really difficult to implement and I have several "satisficing" solutions implemented, but I think it ought to be a common problem so maybe there is something matured and well abstracted out there. It could even/also be a design pattern common to industry applications. Have you seen anything? cheers Siemen
