Dear @lchill2,

Thank you for inviting me to review your Project johnbeve#4! I am glad you were able to open up this pull request. Below are my comments.

I have copy and pasted your problem here, please correct me if I am missing any other parts of your project.

(1) Level-8 Kata Description: Retrieve at least 3 of Plato's works using a SPARQL query.

Solution: PREFIX wd: http://www.wikidata.org/entity/ PREFIX wdt: http://www.wikidata.org/prop/direct/ PREFIX schema: http://schema.org/ PREFIX rdfs: http://www.w3.org/2000/01/rdf-schema#

SELECT ?work ?author WHERE { ?work wdt:P50 ?author . FILTER ( ?author = wd:Q859) } LIMIT 5

This SPARQL query successfully retrieves at least three of Plato's works. Well done!

I have two suggestions, if I may. I suggest that when you upload these SPARQL queries that you separate the WHERE clause from the SELECT line to make things clearer by moving it a line below. Secondly, make sure you move your overall query down a few lines so that they are separate from Beverley's text. Or you can make dividing lines by underscoring three times in Github like so "___" (without the quotes when you actually do it).

Again, great job and thanks for allowing me to review your project!

Best,
Jaron
