Astrometry accuracy is an important component of the LSST Design Reference Mission. Indeed, LSST astrometry will deliver parallaxes, proper motion amplitudes, and perturbations at the milliarcsecond level (or better) for stars as faint as R=26. It is not too early to start developing the astrometric Requirements for the LSST design, creating a network of deep astrometric standards, and for simulating and designing the software pipeline. Among the more challenging problems involve dealing with the short exposure times, segmented focal plane, and atmospheric refraction. Astrometric accuracy must be maintained and quantified from the small scales (sub-pixel) to the largest (computing coordinates in the ICRS). Current plans will be discussed, and suggestions from potential users (needs, algorithms, architecture, etc.) will be solicited.
