Welcome to the 300th Weekly Summary!

The weekly newsletter was started by Lydia
<https://www.wikidata.org/wiki/User:Lydia_Pintscher_%28WMDE%29> at the very
beginning of the Wikidata project, even before the first deployment, to
keep the community informed about the developments, the new projects and
tools. More than five years later, the newsletter is still there, its
content powered by the community, and sent every week all along the years.
I wanted to say a warm "thank you!" to each person who helped filling the
Weekly Summary <3

Over the past years, as you know, Wikidata has grown a lot. More data, more
tools, more editors and reusers, more exciting projects led by the
community. The Weekly Summary has evolved with us, and the 300th edition
seems a good moment to ask you all your suggestions about the newsletter,
how it could continue evolving, and how you would like to improve it.

On that purpose, you can find *a feedback page
<https://www.wikidata.org/wiki/Wikidata:Status_updates/Feedback_300th_edition>*
to express all your ideas about the Weekly Summary. We're very interested
to know more about your reading habits, the parts you're more or less
interested in, the new topics you would like to share with the community.
Thanks in advance for filling it.

I stay available anytime to discuss with you, feel free to contact me if
you have any question or concern! Cheers, Léa

A selection of cool tools on Wikidata

*Here are a few tools that are recommended by some Wikidata community
members. External websites, gadgets or scripts, they are very useful for
Wikidata editors or users!*

   - The *Wikidata Query Service <https://query.wikidata.org/>* is an
   infinite source of amazing data and one of the best ways to explore and use
   Wikidata. (TweetsFactsAndQueries
   <https://www.wikidata.org/wiki/User:TweetsFactsAndQueries>)
   - *QuickStatements <https://www.wikidata.org/wiki/Help:QuickStatements>*
   is a powerful tool that can edit or add Wikidata item *en masse*, via a
   text editor or importing a spreadsheet. (Éder Porto via Facebook)
   - *Mix'n'match <https://tools.wmflabs.org/mix-n-match/#/>* (manual
   <https://meta.wikimedia.org/wiki/Special:MyLanguage/Mix%27n%27match/Manual>),
   which helps us to interlink Wikidata with the rest of the web and the
   world :-) (Spinster <https://www.wikidata.org/wiki/User:Spinster>,
   Siobhan via Twitter)
   - *WikiShootMe! <https://tools.wmflabs.org/wikishootme>* allows you to
   see Wikidata items plotted out on a map and shows you whether they have
   images or not. (Ham II <https://www.wikidata.org/wiki/User:Ham_II>)
   - Yair Rand's *WikidataInfo
   <https://www.wikidata.org/wiki/User:Pigsonthewing/Setup#On_Wikipedia>
   script* adds the QID of the equivalent Wikidata item to the page being
   viewed (on sister projects), along with its Wikidata label and description.
   (Andy Mabbett <https://www.wikidata.org/wiki/User:Pigsonthewing>)
   - *Recoin <https://www.wikidata.org/wiki/Wikidata:Recoin>* measures the
   degree of completeness of relevant properties of a Wikidata item and
   suggests any relevant statements that can be added to the item. (
   Rachmat04 <https://www.wikidata.org/wiki/User:Rachmat04>)
   - *Template:Wikidata list
   <https://www.wikidata.org/wiki/Template:Wikidata_list>* ("Listeria")
   Self-updating lists on wiki pages, to drive projects and show results. Over
   14,000 <https://tools.wmflabs.org/listeria/botstatus.php> now live. (
   Jheald <https://www.wikidata.org/wiki/User:Jheald>)
   - *DuplicateReferences gadget* adds a link to copy references and add
   them to other statements on the same item. (PKM
   <https://www.wikidata.org/wiki/User:PKM>)
   - *checkConstraints gadget* adds notifications on the interface to
   easily notice the violation of constraints
   <https://www.wikidata.org/wiki/Help:Property_constraints_portal> and
   help people fixing them (Léa
   <https://www.wikidata.org/wiki/User:Lea_Lacroix_%28WMDE%29>)
   - *Resolve authors
   
<https://tools.wmflabs.org/sourcemd/new_resolve_authors.php?name=Jane+Smith&doit=Look+for+author>*
   lists scientific articles with the property author name string (P2093) and
   groups them on the basis of co-authors and topic, which helps to
   distinguish people referred to by identical name strings. (Daniel
   Mietchen <https://www.wikidata.org/wiki/User:Daniel_Mietchen>)
   - The *Wiki Loves Monuments map <https://maps.wikilovesmonuments.org/>*
   is powered by Wikidata. You can look for a city and find the monuments
   around. (Stefano Sabatini via Facebook)
