I agree: the generation time (or creation time as I called it in the timeliness use case) belongs to the process dimension. However, the use case mentions another time: the access time. Both, b and c, were created by using x and before using x it had to be retrieved from the Web. The use case demonstrates that information about the access time might be relevant for timeliness assessment (due to missing information about the creation time of x in the case of Carol's data creation). The question is, to which of the dimensions in the Content category does the access time belong. I think it doesn't fit in one of the proposed dimensions. Instead, I suggest to add another dimension, called "Data Access", here. This dimension comprises all kinds of information about the access of data items on the Web. This includes not only access time but, for instance, information what server has been accessed as well as the provider/operator of the server. Such information might also be relevant in other information quality assessment scenarios not just timeliness. For instance, in the other use case discussed today - simple trustworthiness: here we have Alice providing a data publishing server. Someone may decide not to trust any data accessed from this server because he/she thinks Alice is not trustworthy and may have manipulated Bob's and Carol's data provided by her server. And again, it's not just about the access of the assessed data itself but also about the access of source data as the timeliness use case illustrates. Greetings, Olaf
