System and method for accessing private digital content

Abstract: Method for providing access to private digital content owned by an owner and installed on a content server, wherein a content manager server has a number of clients potentially interested in the private content, the method comprising the following steps performed at a content management server being informed that the owner has installed private content on a content server; obtaining a delegate token from the content server; receiving a query for the private digital content from a client of the number of clients of the content management server; providing said client with a token using the delegate token enabling the client to access the private content.

Element manager common gateway architecture system and method

Abstract: A common gateway architecture designed to be generic across different types of network elements and different network protocols, permitting network elements to be added incrementally without recompilation of the entire network element manager, thus reducing overall software maintenance overhead.

Discovery Web Service

Abstract: This invention concerns an arrangement for identifying a data model of at least one service (2103, 2104, 2105), the arrangement comprises a discovery service (2106), comprising storage means for storing data models of the at least one service and for storing a relationship between the data models, and the arrangement comprises inspection means for gathering data models of a service and for establishing relationship between the data models and data models of the at least one service. The invention also concerns a data federation method for identifying a data model of at least one service, by inspecting a service and deriving a data model of the service, establishing a relationship between already known data models of the at least one service, and providing the data models of these services and the relationship between the data models.

Modeling performance of a parallel streaming engine: bridging theory and costs

Abstract: While data are growing at a speed never seen before, parallel computing is becoming more and more essential to process this massive volume of data in a timely manner. Therefore, recently, concurrent computations have been receiving increasing attention due to the widespread adoption of multi-core processors and the emerging advancements of cloud computing technology. The ubiquity of mobile devices, location services, and sensor pervasiveness are examples of new scenarios that have created the crucial need for building scalable computing platforms and parallel architectures to process vast amounts of generated streaming data. In practice, efficiently operating these systems is hard due to the intrinsic complexity of these architectures and the lack of a formal and in-depth knowledge of the performance models and the consequent system costs. The Actor Model theory has been presented as a mathematical model of con- current computation that had enormous success in practice and inspired a number of contemporary work in this area. Recently, the Storm system has been presented as a realization of the principles of the Actor Model theory in the context of the large scale processing of streaming data. In this paper, we present, to the best of our knowledge, the first set of models that formalize the performance characteristics of a practical distributed, parallel and fault-tolerant stream processing system that follows the Actor Model theory. In particular, we model the characteristics of the data flow, the data processing and the system management costs at a fine granularity within the different steps of executing a distributed stream processing job. Finally, we present an experimental validation of the described performance models using the Storm system.

Import2vec learning embeddings for software libraries

Abstract: We consider the problem of developing suitable learning representations (embeddings) for library packages that capture semantic similarity among libraries. Such representations are known to improve the performance of downstream learning tasks (e.g. classification) or applications such as contextual search and analogical reasoning. We apply word embedding techniques from natural language processing (NLP) to train embeddings for library packages ("library vectors"). Library vectors represent libraries by similar context of use as determined by import statements present in source code. Experimental results obtained from training such embeddings on three large open source software corpora reveals that library vectors capture semantically meaningful relationships among software libraries, such as the relationship between frameworks and their plug-ins and libraries commonly used together within ecosystems such as big data infrastructure projects (in Java), front-end and back-end web development frameworks (in JavaScript) and data science toolkits (in Python).

Prototyping graphical user interfaces

Abstract: A method, system, and computer readable medium is described for creating a prototype GUI (500) for conversion into an actual GUI (552, 554) whose appearance when displayed matches the appearance of the prototype GUI. In some situations, multiple personnel may participate in the process, such as a non-technical GUI designer (540b) that specifies the prototype GUI appearance information and a technical GUI developer (550b) that specifies various non-appearance information for a corresponding actual GUI. A prototype GUI is first created based on layout and other appearance information specified for various GUI elements, and corresponding proxy GUI objects (540) are generated that store appearance information but not various non-appearance information used as part of an actual GUI. Proxy GUI objects for a prototype GUI can then be converted into actual GUI objects (550) for use with an actual GUI, and various non-appearance information can be specified for the actual GUI objects in various ways.

Bundled authorization requests

Abstract: A framework, which conforms to the OAuth standard, involves a generic OAuth authorization server that can be used by multiple resource servers in order to ensure that access to resources stored on those resource servers is limited to access to which the resource owner consents. Each resource server registers, with the OAuth authorization server, metadata for that resource server, indicating scopes that are recognized by the resource server. The OAuth authorization server refers to this metadata when requesting consent from a resource owner on behalf of a client application, so that the consent will be of an appropriate scope. The OAuth authorization server refers to this metadata when constructing an access token to provide to the client application for use in accessing the resources on the resource server. The OAuth authorization server uses this metadata to map issued access tokens to the scopes to which those access tokens grant access.
