... We describe one detailed base level model, a component model for Quantity, which is a generalisation of previous informal proposals. ... In Figure 1 we propose a model for this area. The main difference between this and other proposals (see http://www.ivoa.net/twiki/bin/view/IVOA/IVOADMQuantityWP for IVOA Quantity data modeling resources ) is that we believe that the core concept is the measurement , which we define as the act of assigning a value plus error to a property, not the quantity itself. ...

It is now possible to specify multiple log files, each with a fully customizable format. ... Multiple log files are implemented as part of the mod_log_config module which as of Apache 1.2 is the default log module.

. The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges in the near infrared. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: F105W (Y) blue; F125W (J) green; F160W (H) red. NASA/ESA/G. Illingworth/R.
