Become involved with DLESE development

DLESE is being built in a distributed fashion. Library collections and services are being built, hosted, and managed by a variety of groups and individuals across the nation. Collections are organized sets of resources where the particular organization focus and intent of the collection is specified in a 'collections scope' statement (see example scope statement from the Atmospheric Visualization Collection). A collection is held in the library infrastructure as a set of metadata records describing items in the collection.

Services are tools or activities that provide value to the DLESE community. They can be computer-mediated (e.g. interfaces for searching the library or mechanisms to support online peer review, etc.) or human-mediated (e.g. workshops or training events).

Individuals and groups are encouraged to contribute to the development of DLESE. DLESE has adopted library policies, standards and technologies to help ensure that distributed building efforts yield a coherent and reliable end-user library experience. This library development area gives more details about these policies, standards and technologies from a number of perspectives.

What is available for developers

Collections: A core part of any library are its collections. This area provides information about how to build or contribute digital collections to DLESE. Designing digital collections offers Earth system science educators a new opportunity to contribute to the advancement of knowledge and educational practice in this field, and to tailor the library to better support specific teaching and learning needs. The library provides a number of services and tools to support collection creation and collection management processes.

Metadata: Metadata is a structured description of a library resource. For instance, a data set may have a title, a brief description, and a location and time where the data were collected. A description of a lesson plan will include the intended grade level for this particular curricular resource, technical requirements, and resource type. Metadata plays a central role in DLESE and the NSDL, and effectively defines the library's contents. Many library services, such as searching and browsing interfaces, operate on the metadata within the library. This area provides details on the metadata frameworks used in DLESE collections and services.

Services and APIs: This portal contains information about the Web-based services, APIs and protocols that are available for remotely accessing the library's search capabilities, XML metadata and other content, and contains links to tools and documentation for developers to begin using the services.

DLESE Collection System: Developed by the DLESE Program Center, this tool is used by community members and catalogers, etc. to catalog educational resources into DLESE. Resources must be within the scope of the DLESE collection.
