Partial high-level structure of OBI classes.

<p>OBI classes are shown in blue. Classes imported from BFO, IAO and other external ontologies are shown in orange, purple and dark red, respectively. Some example subclasses, such as <i>device</i> and <i>processed specimen</i> are included to illustrate the use of the class <i>processed material</i>.</p

Anatomy of a web-based identifier.

<p>An example of an exemplary unique resource identifier (URI) is below; it is comprised of American Standard Code for Information Interchange (ASCII) characters and follows a pattern that starts with a fixed set of characters (URI pattern). That URI pattern is followed by a local identifier (local ID)—an identifier which, by itself, is only guaranteed to be locally unique within the database or source. A local ID is sometimes referred to as an “accession.” Note this figure illustrates the simplest representation; nuances regarding versioning are covered in Lesson 6 and <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.2001414#pbio.2001414.g005" target="_blank">Fig 5</a>.</p

Contributions and roles related to content as they correspond to identifier creation versus identifier reuse.

<p>The decision about whether to create a new identifier or reuse an existing one depends on the role you play in the creation, editing, and republishing of content; for certain roles (and when several roles apply) that decision is a judgement call. Asterisks convey cases in which the best course of action is often to correct/improve the original record in collaboration with the original source; the guidance about identifier creation versus reuse is meant to apply only when such collaboration is not practicable (and an alternate record is created). It is common that a given actor may have multiple roles along this spectrum; for instance, a given record in monarchinitiative.org may reflect a combination of (a) corrections Monarch staff made in collaboration with the original data source, (b) post-ingest curation by Monarch staff, (c) expanded content integrated from multiple sources.</p

Measuring glucose concentration in blood.

<p>The large boxes represent instances of processes and their participants. The <i>collecting specimen from organism</i> process takes place first. In this process, a <i>syringe</i> is used to draw blood from the mouse. At the end of this process a tube contains the <i>blood specimen</i>. In a second process, this specimen is used in an <i>analyte assay</i>, which measures the concentration of glucose in the blood. A <i>glucometer</i> is used to make this measurement. The <i>analyte role</i> inheres in the <i>glucose molecules</i> scattered throughout the <i>blood specimen</i>. This <i>planned process</i> achieves the <i>analyte measurement objective</i>.</p
