JSTOR and the Harvard University Library are pleased to announce that the initial production release of JHOVE (the JSTOR/Harvard Object Validation Environment, pronounced "jove") is now available at <http://hul.harvard.edu/jhove/>. JHOVE is an extensible framework for format-specific object identification, validation, and characterization. Format identification answers the question, "I have an object; what format is it?" Validation answers the question, "I have a format purportedly of format F; is it?" Characterization answers the question, "I have an object of format F; what are its salient properties?" This version, Rel. 1.0 (2005-05-026), includes modules that support the following formats: o AIFF, AIFF-C o ASCII o GIF 87a, 89a o HTML 3.2, 4.0, 4.01, XHTML 1.0 and 1.1 o JPEG, JFIF, Exif 2.0 and 2.1, SPIFF, JTIP, JPEG-LS o JPEG 2000 JP2, JPX o PDF 1.0-1.6, PDF/X-1, -1a, -2, -3, Tagged PDF, Linearized PDF, PDF/A-1 o TIFF 4.0-6.0, Class B, G, P, R, Y, F, TIFF/IT, TIFF/EP, Exif 2.0 and 2.1, GeoTIFF, TIFF-FX, RFC 1314, DNG o UTF-8 o WAVE, BWF o XML 1.0 Still image metadata is reported in the form of NISO Z38.97/MIX schema; audio metadata is reported in the form of AES-X098B schema. Detailed release notes, documentation, and tutorial information are available on the JHOVE web site <http://hul.harvard.edu/jhove/>.
