  In this paper we report the first stages of an investigation into the X-ray
properties of extragalactic jets. Our approach is to subject all sources for
which X-ray emission has been detected by Chandra to uniform reduction
procedures. Using Chandra archival data for 106 such sources, we measure X-ray
fluxes in three bands and compare these to radio fluxes. We discuss the sample,
the reduction methods, and present first results for the ratio of X-ray to
radio flux for jet knots and hotspots. In particular, we apply statistical
tests to various distributions of key observational parameters to evaluate
differences between the different classes of sources. Subsequent papers will
deal with various ramifications such as considerations of how well the
observational data fulfill expectations of the different radiation processes
proposed for the knots of FRI radio galaxies and quasars.
