Abstract: A computer system enables instances of properties (e.g., of resources such as files in a file system) to be selectively synchronized with each other. Each instance of a property may have a plurality of versions. A primary version of the property is shared (and synchronized) among all property instances. Each property instance may also have its own secondary version of the property. Each property instance has its own effective version handle, which points to either the property's primary version or the property instance's secondary version of the property. A comparison is performed between a version state of the property's primary version and a version state of the secondary version of a first instance of the property to produce comparison result output. An instance state is exposed to indicate: (1) the version pointed to by the first instance's effective version handle; and (2) the comparison result output.

Abstract: A computer-implemented system and method for staged resource querying addresses limitations of traditional file systems, which provide a flexible, scalable framework for organizing, managing, and querying diverse digital resources across multiple providers. The method receives a query specifying a sequence of stage types, each defining processing and grouping of items. It executes operations to process input items through these stages, creating a dynamic graph structure of grouped output items. This includes taking items from a resource iterator, processing them through specified stages, and organizing results into groups. The method enables incremental processing of resources, allowing efficient handling of large datasets and complex queries. It provides mechanisms for propagating items through the stage graph, offering fine-grained control over resource processing and grouping at each stage.
