Intellectually, I completely understand. Practically, I still advocate putting publishing the linked data as soon as possible. Knowledge is refined over time. The data being published is not incorrect nor invalid, just not as good as it could be. Data aggregators will refresh their stores and old information will go to "Big Byte Heaven”. It is just like a library collection. The “best” books are collected. The good ones get used. The old ones get weeded or relegated to off-site storage. What remains is a current perception of truth. Building library collections is a process that is never done nor never perfect. Linked data is a literal reflection of library collections, therefore linked data is never done nor never perfect either. URIs will break. Books will be removed from the collection. URIs will go stale. The process of providing linked data is a lot like painting a painting. The painting is painted as a whole, from start to finish. One does not get one corner of the canvass perfect and move on from there. An idea is articulated. An outlined is drawn. The outline is refined, and the painting gradually comes to life. Many times paintings are never finished but worked, reworked, and worked some more. If the profession looks to make perfect its list of URIs, then it will never leave the starting gate. I know that is not being advocated, but since one can not measure the timeless validity of a URI, I advocate that the current URIs are good enough. There is an understanding of a commitment to updating them and refining them in the future. — Eric Morgan
