1. A non-transitory computer storage medium storing computer-useable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform operations for facilitating portability of web meeting interactions, the operations comprising: receiving, from a client device that is associated with a participant identifier, at least a first annotating input for a first instance of a web meeting identifier, wherein the received first annotating input is stored independently from a recording of a first web meeting that corresponds to the first instance; processing the received first annotating input to include therein a first unique descriptor that references the participant identifier, the first instance, a time, and the recording; generating an interaction record that includes the processed first annotating input; transmitting, to the client device, at least a first portion of the interaction record that includes the processed first annotating input; receiving, from the client device to export to a second instance of the web meeting identifier, the processed first annotating input selected from the transmitted first portion of the interaction record; generating a second annotating input that is based on a portion of the selected first annotating input, the generated second annotating input including a second unique descriptor that at least references the second instance; and providing, to the client device for the second instance of the web meeting identifier, at least a second portion of the interaction record that includes the generated second annotating input, the generated second annotating input to be provided in a second web meeting that, when instantiated, corresponds to the second instance, wherein the first meeting and the second web meeting are different occurrences.
