Hi Laerte, DSpace will never ship with a "complete solution" for preservation. It is likely to only ever provide basic preservation tools, as it never was built as a complete preservation system (and as you noted, there are other systems built for that purpose). As you are surely aware, preservation itself is quite complex (and often based on local needs/goals/laws/requirements/content). Attempting to build a single system that can do what DSpace already does while also performing all preservation activities would be highly complex. I'm unaware of any system that can achieve both.
Because of this, DSpace has always concentrated more on ingest and access modes, with a primary goal of ensuring important research/content is easily findable on the web, etc. It leaves more complex preservation details to other systems, but attempts to provide a very basic level of preservation (checksum validation) along with ways to easily export your data into preservation-ready formats (AIP format, DSpace Simple Archive Format, etc). As you noted, other compatible systems exist that concentrate more on preservation. Archivematica is one. Another is DuraCloud (which has more of a concentration on preservation storage): http://duracloud.org/ It's also worth mentioning here that there is a "connector" specific to DuraCloud already which lets you "sync" DSpace AIPs to an external storage platform and/or DuraCloud: https://wiki.duraspace.org/display/DSPACE/ReplicationTaskSuite It's likely that same sort of connector could be customized to send data to Archivematica (or another system).
