Simple matrix keys from Excel spreadsheets

Abstract

An innovative workflow is presented, leading from a simple character and taxon matrix, prepared in an Excel spreadsheet, to a functioning free-access matrix key, stored in SDD (Structured Descriptive Data) format and presented in the flash-based free-access key player IBIS-ID directly on the web. The subset of matrix key functionality supported by this workflow include categorical and quantitative characters, multiple character states for a given taxon, taxon, character, and state illustrations, and a single character grouping level. Advanced features such as complex character or taxon trees, character dependency, or taxon-specific state images are not supported. The workflow aims to attract new contributors for which the learning curve of special purpose matrix-key editing software is too steep.
