Abstract: Systems and methods for filtering collaboration activity to present in an activity feed. A cloud-based collaboration system is configured to identify collaboration interactions that users have taken over collaboration objects. Some of the collaboration objects or interactions are subject to access permissions as well as policy-based access rules. When a subject user interacts with a user interface, system components select a first set of user interaction events that in some way pertain to the subject user. A first filtering pass applies a first filter to determine object access permissions. After reducing the first set to a smaller second set, then a second filter corresponding to policy-based access rules is applied to the second set to form a still smaller third set of user interaction events. Characteristics of user interaction events in the third set are used to generate user-specific activity feed entries that are presented in a user interface.

Abstract: Systems for managing multiple shared content objects using access tokens that cover the multiple shared content objects are disclosed. A method commences upon assigning the shared content objects to have individual permissions grantable to two or more users. A user configures a shareable unit to include attributes that describe a plurality of constituent shared content objects stored on one or more storage devices in the cloud-based storage system. An administrator or other user configures allow/deny access privileges to the shareable unit. Upon receiving a request from a user to access the shareable unit, a single access token is generated to provide access to the shared content objects that comprise the shareable unit. Ongoing access to the shareable unit is accomplished using the single access token, without the need to provision an access token or tokens pertaining to individual ones of the constituent shared content objects of the shareable unit.

Abstract: Scalable architectures, systems, and services are provided herein for generating jobs by applying user-specified metadata rules to metadata events. More specifically, the scalable architecture described herein uses metadata to drive automations and/or polices in a cloud-based environment. In one embodiment, the architecture integrates a metadata service with an event-based automation engine to automatically trigger polices and/or automations based on metadata and/or changes in metadata changes. The metadata service can include customizable and/or pre-build metadata templates which can be used to automatically apply a metadata framework (e.g., particular fields) to files based on, for example, the upload or placement of a particular file in a particular folder. The architecture also provides for advanced metadata searching and data classification.

Abstract: Techniques are disclosed for enabling synchronization of items (e.g., folders or files) in a cloud-based environment. In one embodiment, a method comprises, upon receiving a request from a collaborator to synchronize an item stored in the workspace, verifying if the collaborator has permission for downloading the item. The method further comprises, if the collaborator has permission for downloading the item, sending the item to the collaborator. The method further comprises synchronizing the item by automatically pushing an updated version of the item unilaterally from the cloud-based environment to the collaborator regardless of whether the collaborator has performed any modification to the sent item. Among other advantages, embodiments disclosed herein provide capabilities to synchronize items in cloud-based platforms, especially where items are often opened/edited among the collaborators.

Abstract: System and methods for summarizing collaboration activity events into a plurality of pages that are then scored with respect to user-specific relevance that is based on a set of comprehensibility characteristic parameters. The collaboration activity events are summarized into groups of activities based on certain common attributes that are deemed to have quantitatively measurable relevance to the user. The groups of activities are assembled into a plurality of personalized candidate pages. The candidate summary pages are then scored using a function that includes parameters that serve to quantify how interesting or readable the particular user would find the particular candidate summary page. One or more of the higher scoring candidate summary pages are selected for presentation to the user.

Abstract: Disclosed is an improved systems, methods, and computer program products that use a cluster-based probability model to perform anomaly detection, where the clusters are based upon entities and interactions that exist in content management platforms.

Abstract: A server in a cloud-based environment interfaces with storage devices that store shared content accessible by two or more users. Individual items within the shared content are associated with respective object metadata that is also stored in the cloud-based environment. Download requests initiate downloads of instances of a virtual file system module to two or more user devices associated with two or more users. The downloaded virtual file system modules capture local metadata that pertains to local object operations directed by the users over the shared content. Changed object metadata attributes are delivered to the server and to other user devices that are accessing the shared content. Peer-to-peer connections can be established between the two or more user devices. Object can be divided into smaller portions such that processing the individual smaller portions of a larger object reduces the likelihood of a conflict between user operations over the shared content.

Abstract: Systems for user interface composition in a collaboration environment. A method commences upon identifying a server in a cloud-based environment, wherein the server is interfaced with one or more storage devices that store one or more objects accessible by two or more users. Upon receiving a request to access an object that is stored in the cloud-based environment, the method processes the request to determine if the object has two or more rendering options such as a popup rendering option or a modal rendering option. If so, the method selects one of the rendering options and collects further information such a user profile information and/or a collaboration rulebase, which further information is used to drive composition of formatted object. The adaptively-formatted object is transferred over the network to satisfy the request.

Abstract: Systems for fast views of items in file directories or file folders when interacting with a cloud-based service platform. A server in a cloud-based environment interfaces with one or more storage devices to provide storage of shared content accessible by two or more user devices. A file tree request to view the file directory or file folder of a particular sought after item is issued from an application operating on one of the user devices. Additional file tree items in a file tree hierarchy are prefetched by the cloud-based service platform. The application closes the file tree metadata stream after receiving the portion of the file tree that pertains to the particular item and before receiving the entirety of the metadata pertaining to all of the file tree metadata of all of the items in the directory or folder that contains the particular sought after item.

Abstract: Systems for managing user collaboration over objects stored on a cloud-based service platform. A server in a cloud-based platform maintains a set of read/write metadata that is associated in one-to-one correspondence to stored objects that are accessible by two or more collaborators. The server does not maintain a list of peers that communicate over peer-to-peer connections, rather the server exposes a semaphore for access to the metadata that pertains to a particular one of the stored objects. The server responds to download requests from the collaborators so as to deliver executable signaling protocol computer code to the collaborators' user devices. The signaling protocol code includes semaphore access by the collaborators' user devices using an application programming interface. Two or more accesses over the same semaphore establishes a leader and at least one follower. Corresponding ephemeral peer-to-peer connections are established between the leader and the at least one follower.

Abstract: Shared content is stored at a cloud-based collaboration platform hosted at first network domain. External data processing services are hosted at a second domain. An integration layer situated between the cloud-based collaboration platform and the external data processing services is configured to receive triggering events pertaining to content of the cloud-based collaboration platform. Based on characteristics of the content, communications with the external data processing services are initiated. The communication includes accessing network interfaces to send and receive data between the network domain of the cloud-based collaboration platform and a different network domain of the external data processing services. A plurality of rules are applied to select between a first external data processing service at a first network domain and a second external data processing service at a second domain.

Abstract: Methods, systems and computer program products for extensible content object workflows. A content management system stores a plurality of content objects. The content management system integrates applications, which integrated applications make modifications to the content objects based on computer-aided invocation of workflows. Upon receipt of a message from a first integrated application indicating an intent to invoke a workflow at a second integrated application, the content management system relays information pertaining to the desired workflow to the second integrated application. The workflow of the second integrated application modifies one or more of the content objects or its metadata or other data associated with the workflow. Selection of the second integrated application can be based on attributes of the content objects, and/or can be based on user interactions within a user interface.

Abstract: Systems for managing static assets of web applications. A method embodiment includes identifying a web application that comprises a code base and a set of static assets, then separating the code base of the web application from the set of static assets that are referenced by the web application. The code base is deployed as application services whereas the static assets are deployed as static asset containers. Specifically, the set of static assets referenced by the application services are deployed in containers that are instantiated separately from where the application services are instantiated. Requests to access the application services and requests to access the static assets are tracked by taking performance measurements of the systems that process the accesses. Dynamic scaling of static asset containers is done independently from dynamic scaling of the application services. The dynamic scaling is based on combinations of measured usage and/or any system performance characteristics.

Abstract: Enterprise administrators in a cloud-based environment including a cloud-based server and a repository can selectively impose permissions on items (e.g., files and folders) marked for synchronization (“sync items”). The sync items can be synchronized with the client devices of users by downloading the items along with the permission attributes from the cloud-based server. However, the permissions on those sync items means that any unpermitted changes to the local copies of the sync items do not get uploaded to the cloud-based server. A synchronization client on the client devices detects any changes made locally to the sync items that are not consistent with the permission attributes, and repairs those changes so that the sync items are restored to their most recent states. This ensures that any unauthorized changes made to sync items remain local and do not propagate by the synchronization process to other users.

Abstract: Systems for accessing medical imagery from a cloud-based facility using a browser-like application. A first user (e.g., a physician) identifies a first plurality of medical digital information files that are organized in a first storage structure. The first user's requests a set of first digital information views of the identified medical digital information of the first storage structure wherein the plurality of first digital information views are described by a respective first set of logical view attributes that are associated with the files organized in the first storage structure. A second user (e.g., a second physician) requests a second plurality of digital information views of the first storage structure wherein the second plurality of digital information. The system sends the first digital information views to the first user, and sends the second digital information views to the second user.

Abstract: Methods and systems for online collaboration. A method embodiment facilitates collaborative editing of a cloud-based shared document using a browser-enabled platform native application. A user launches a platform native application and establishes a non-browser connection between the platform native application and a remote cloud-based shared file facility. The non-browser connection operates independently from any browser connections even though the platform native application includes a document editor web app within the embedded browser. A first user retrieves a first user copy of the cloud-based shared document, modifies the document, and shares the modified document so as to be accessible by other collaborating users.

Abstract: Content management in a collaboration system. Ease-of-use of shared content is facilitated. A URL is presented in a user interface. The system determines (e.g., based on user preferences) whether to display the content corresponding to the URL in a browser at the user device, or whether to display the content corresponding to the URL using a non-browser application. If the user device is configured to display the content corresponding to the URL using a non-browser application, then when the user clicks or touches or hovers, or otherwise indicates a selection of a URL, the system displays the content using the non-browser application. In this situation, the system retrieves the content from the collaboration system, stores a local instance of the content in local storage of the user device, and opens the local instance using the non-browser application. Local instance edits are synchronized with the collaboration system using a synchronization protocol.
