Embodiments of the invention provide an event notification method and a server, relate to the technical field of communication, and can solve a problem that various subscription requirements of a subscriber cannot be met due to the fact that a subscription condition is only simple superposition of limited atomic conditions in the prior art. A specific scheme is as follows: the server determines whether an updated resource of a publisher satisfies the subscription condition or not, wherein the subscription condition comprises a composite subscription condition, the composite subscription condition comprises at least one first atomic condition, and the first atomic condition is a condition corresponding to a first resource identifier, a first resource attribute or a data content of a resource instance, the first atomic conditions in the composite subscription condition are combined through a logical relationship, the logical relationship includes "AND", "OR" or "NOT"; and If the updatedresource of the publisher is determined to satisfy the subscription condition, an event corresponding to the updated resource of the publisher is notified to an address of the subscriber correspondingto the subscription condition.
