According to Wikipedia, “In golf, a caddy or caddie is the person who carries a player's bag and
clubs, and gives insightful advice and moral support. A good caddy is aware of the challenges
and obstacles of the golf course being played, along with the best strategy in playing it.” This
quote is emblematic of this project because bioCADDIE is designed to help data producers,
disseminators, and consumers “play their game” in the new era of team science. It will give
players insightful advice and financial support to implement new ideas.
The bioCADDIE team will develop a data discovery index (DDI) prototype which will index data
that are stored elsewhere. The DDI will play an important role in promoting data integration
through the adoption of content standards and alignment to common data elements and high-level
schema. A DDI could provide the means to test the utility of these standards. It could serve as
an incubator to spur the types of quality metrics that currently are being developed around
article metrics, including citation analysis and altmetrics.
Introduction to Boolean Logic
Boolean logic is a system of showing relationships between sets by using the words "AND," "OR,"
and "NOT." (The term Boolean comes from the name of the man who invented this system, George
Boole.) Boolean logic is recognized by many electronic searching tools as a way of defining a
- The Boolean operators AND, OR, NOT can be used to combine search terms in bioCADDIE.
- In bioCADDIE, Boolean operators must be entered in uppercase letters.
Search by Field
Terms may be qualified using bioCADDIE's search field tags. The allowable fields are: title, author and description.
The search field tag must follow the term -- you cannot prequalify.
Tags are enclosed in square brackets.
Example: Lung[title] AND Cancer
Search by Phrase
Used to retrieve a set in which each dataset contains exact phrase.
The search term must be enclosed in double quotes. "AND/OR/NOT" inside double quotes are not treated as boolean logic.
Example: "Lung cancer"[title] AND Cancer
- Boolean operators -- AND, OR, NOT -- must be entered in uppercase letters.
- Boolean operators are processed from left to right.
- Use double quotes to do phrase search.
- Field names must be enclosed in squred brackets.
- If you are using our advanced search constructor to construct the query, please use the "add Criteria" button to add boolean logic.
