Life Sciences Domain Analysis Model
caBIG® Life Sciences Domain Analysis Model (LS DAM) v2.1 has been released. The LS DAM is a shared view of the semantics for Life Sciences, which includes hypothesis driven basic and pre-clinical research as well as discovery sciences. It is aligned, where appropriate, with the Clinical Sciences BRIDG model, which covers protocol driven clinical research. The LS DAM is a foundational component for achieving semantic interoperability among the various applications across caBIG® and is bound to the ISO 21090 data type standard.
The major changes in this release are described in the Release Summary and include:
- Creation of a Life Sciences Scope Statement
- Update to the Molecular Biology core component to promote consistent use of the model when dealing with physical entities and/or information about those entities
- Expansion of Experiment Core(formerly called the Generic Assay model) to include ExperimentalParameters
- Addition of the BRIDG aligned Performer role based class which was identified as a gap through analysis of Pathology Imaging Use Cases
- Representation for biologic models by inclusion of classes for CellCulture, CellLine, MicrobiologicCulture, subSpeciesRank identified through analysis of Pathology Imaging Use Cases
- Support for material compositions by addition of MaterialRelationship class (and removal of caNanoLab derived specializations of Material that can now be handled more elegantly)
- Further development of the Container concept
- Addition of attributes to the Software class
- Common Biorepository Model mappings are documented and added as tags in the UML model
For a complete list of modifications and additions to the LS DAM v 2.1, please see the Release Notes and Model Documentation.

We have released a new version of the NanoParticle Ontology(NPO). This version includes new terms that describe “scales of measurement” and nanomaterials. We made some modification to the nanomaterial branch and added new terms based on ISO terminology.

NPO VISUALIZATION: To browse and visualize the NPO, please go to http://purl.bioontology.org/ontology/npo .
NPO INCLUDED IN NCI METATHESAURUS: The NPO is now included in the NCI metathesaurus (NCIm), which can be accessed at http://ncimeta.nci.nih.gov/ .
The NCI metathesaurus contains about 3,600,000 terms from over 76 vocabularies, and these terms are mapped to about 1,400,000 biomedical concepts. Terms from multiple vocabularies that are mapped to a single biomedical concept allows the user to choose from the multiple vocabularies to annotate data. Simultaneously, this facilitates discovery of vocabularies unknown to the user. By the inclusion of NPO into the NCI metathesaurus, we expect that NPO accessibility and usage will be extended within the NCIm; NPO will add semantics into the NCIm; and that NCIm users will be able to take advantage of the knowledge provided by NPO.
NPO TERM SUGGESTION: The NCI term suggestion application allows for users to suggest terms for NPO. To suggest terms for NPO, you may use the NCI term suggestion application, available at: http://ncitermform.nci.nih.gov/
