Thanks a lot, Sebastian for your answer.
I have one remaining question,
for 2017 and 2019, there are note files?
I don't understand this question. We are quite happy that we are finally
able to stabilize and speed up regular mapping releases. So it will get
better in the future.
is there any way to generate this, in
http://live.dbpedia.org/changesets/, there is an hourly changeset,
there is not any way to obtain a type and mapping files for the
desired date?
I don't know your use case, but theoretically you could produce
arbitrary time slices and snapshots of mappingbased/instance types from
the changesets, right?
Please post, if you are going to implement this.
Note that we are doing a server wipe and fresh install of
live.dbpedia.org next week, so the changesets will be unavailable for
some days.

query can be built on the website, but note that these are
unreleased due to:
- website is not working 100%
- small encoding problem of the releases duer to RDF parser
All the best,

Hi all,
I am Martín Domínguez, a researcher from Universidad de
Córdoba, Argentina. We make researching by using DBpedia dumps,
and the latest ones, in the format we use, are available for 2016
(https://wiki.dbpedia.org/develop/datasets/downloads-2016-10).
We specifically use the "Instance Types" and "Mapping-based
properties" files, which are available for 2016 and previous dates.
Actually, we found DBpedia Live, and I found the last dumps and
the changesets described in
(https://wiki.dbpedia.org/online-access/DBpediaLive#4%20Important%20Pointers).
After reading this documentation, it is possible to have a new
Dump up to date, but, is it possible only extracting dumps for
"Instance Types" and "Mapping-based properties"?.
We also need to obtain those files not for the latest update, but
also for a given previous date, it is possible?
regards!
Martín
