The Strand Map Service (SMS) APIs provide the ability to build custom interactive strand map interfaces for a variety of applications. The APIs include a Javascript API that lets developers insert interactive Strand Maps into Web pages and place custom content into the maps and a REST API that lets developers search and navigate the Strand Map information space and access objects and visualizations in number of formats including XML, OWLLite, SVG, PDF, PNG, TIFF, and JPEG.

The APIs access a database based on the learning goals from the AAAS Benchmarks for Science Literacy and the visualizations from the AAAS Atlas of Science Literacy (AAAS Project 2061), which demonstrate the connectedness of ideas and skills that students should develop over time.

The SMS is produced by researchers from the University of Colorado at Boulder and Digital Learning Sciences, and is based on the strand maps developed by Project 2061 at the American Association for the Advancement of Science and published in the Atlas of Science Literacy, Volumes 1 and 2 (2001 and 2007, AAAS Project 2061 and the National Science Teachers Association).

Examples and Demos in Use

Prerequisites

End-user

  • Javascript enabled browser

Developer

  • Requirements are dependent on intent. Since the API is called from a central location on NSDL servers, it is possible to make a functional interface with a server to host the webpage, HTML, JavaScript, and CSS. More complex functionality may require a server-side web technologies and/or a database. For more information see theSMS JavaScript API implementation instructionsand theexample code.
