METHODS AND A COMPUTING DEVICE FOR CARRYING OUT DATA COLLECTION

According to an implementation, a host computing device receives, from a first computing device, a data collection request of a first user. The data collection request indicates a data point (whose characteristics are defined in a mark-up language schema) that is to be the subject of the data collection and identifies a second user as provider of a value for the data point. The host computing device notifies the second user of the data collection request and receives, from a second computing device, a request of the second user for the data point to be assigned a plurality of categories. In response to the request of the second user, the host computing device extends the mark-up language schema to characterize the plurality of categories within the mark-up language schema.
