We introduce the AcousticBrainz project, an open platform for gathering music information. At its core, AcousticBrainz is a database of music descriptors computed from audio recordings using a number of state-of-the-art Music Information Retrieval algorithms. Users run a supplied feature extractor on audio files and upload the analysis results to the AcousticBrainz server. All submissions inclu...

Many business web-based applications do not offer applications programming interfaces (APIs) to enable other applications to access their data and functions in a programmatic manner. This makes their composition difficult (for instance to synchronize data between two applications). To address this challenge, this paper presents Abmash, an approach to facilitate the integration of such legacy we...

In this paper we propose an open source/open architecture framework for developing organ level surgical simulations. Our goal is to facilitate shared development of reusable models, to accommodate heterogeneous models of computation, and to provide a framework for interfacing multiple heterogeneous models. The framework provides an intuitive API for interfacing dynamic models defined over spati...

Leveraging Application Programming Interfaces (APIs) has been widely acknowledged as a valuable approach to software and system design that have promoted the acceleration of products and services development by allowing the decoupling of interface design from service implementation details. Many organizations in the news and journalism industry have adopted and promoted this API oriented approa...

We present hyp, an open-source toolkit for the representation, manipulation, and optimization of weighted directed hypergraphs. hyp provides compose, project, invert functionality, k-best path algorithms, the inside and outside algorithms, and more. Finite-state machines are modeled as a special case of directed hypergraphs. hyp consists of a C++ API, as well as a command line tool, and is avai...

In this study, a system is presented and analyzed that automatically translates a model described within the Modelica framework into the Discrete Event System Specification (DEVS) formalism. More specifically, this work interfaces the open-source implementation of Modelica, OpenModelica, and one particular software tool for DEVS modeling and simulation, the PowerDEVS environment, which implemen...

This paper describes the FeatSynth framework, a set of open-source C++ classes intended to make it as easy as possible to integrate feature-based synthesis techniques into audio software. We briefly review the key ideas behind feature-based synthesis, and then discuss the framework’s architecture. We emphasize design choices meant to make the framework more flexible and straightforward to use. ...

This paper presents an open-source application for evaluating competing clinical trial (CT) designs using simulations. The S4 system of classes and methods is utilized. Using object-oriented programming provides extensibility through careful, clear interface specification; using R, an open-source widely-used statistical language, makes the application extendible by the people who design CTs: bi...

Ontology is one of the important semantic web enablers. However, there are few open Application Programming Interfaces, or APIs, to support developers in terms of building ontology. Often, the developers are asked to use a specific tool that does not open its API in a developer friendly manner. Thus, we provide a set of open APIs for ontology building. These APIs aim to help ontology building t...
