1. A system comprising: a database interface; a communication interface; and collaboration circuitry in communication with the database interface and the communication interface, the collaboration circuitry configured to: retrieve defined roles assigned to geographically distributed entities and communication pathway preference information for the geographically distributed entities from the database interface; generate an event notification for an event for distribution to the geographically distributed entities; implement an adaptable subscription model that is operable to select specific entities among the geographically distributed entities to which to send the event notification, where the adaptable subscription model is operable to identify the specific entities responsive to the defined roles in comparison to the event; tune the adaptable subscription model by subscribing the geographically distributed entities to additional events, where the additional events are selected responsive to the defined roles of the geographically distributed entities; determine the specific entities to which to send the event notification to based on the adaptable subscription model; and determine communication pathways, supported by the communication interface, for sending the event notification to the selected entities, responsive to the communication pathway preference information for the selected entities; digital collaboration workspace circuitry in communication with the database interface and the communication interface, the digital collaboration workspace circuitry configured to: provide a newsfeed comprising event notifications for events that a system subscriber is following; aggregate communications responsive to the event notifications to obtain an event conversation; insert the event notifications and event conversation into the newsfeed to obtain an enhanced newsfeed; and generate a digital collaboration workspace user interface comprising the enhanced newsfeed; persistent status circuitry configured to: promote specific event notifications to a persistent status; place the event notifications promoted to, persistent status as a persistent note in a prioritized location on the digital collaboration workspace user interface; and retain the persistent note in the prioritized location until a pre-determined condition is met; workspace update circuitry configured to process subsequent events and subsequent event notifications to update the newsfeed provided by the digital collaboration workspace circuitry; and knowledge capture circuitry configured to perform a knowledge capture process to: store a collaboration occurrence in a knowledge base, process the collaboration occurrence to identify relevant metadata tags, and generate additional documentation comprising the metadata tags.
