Re: Outreachy 2020-2021 - Neo4j - Weekly reports.
Hi all. I wanted to inform the tasks I worked on this week: Jan 16 - Jan 22 . - Add EXISTS constraints for properties. - Develop put method. - Enable test of the put & get methods. - Switch to fixed version docker image 'neo4j:4.2.2-enterprise' instead of 'enterprise' tag. My code is here: https://github.com/mgov88/gora/tree/GORA-663 I have a question, in Neo4j the null value represent the absence of the property/relation: "In Neo4j, since there is no table schema or equivalent to restrict possible properties, non-existence and null are equivalent for node and relationship properties. That is, there really is no such thing as a property with a null value; null indicates that the property doesn’t exist at all." https://neo4j.com/developer/kb/understanding-non-existent-properties-and-null-values/ I added an attribute in the mapping file to specify if the EXISTS constraint should be applied, because in the tests sometimes the field values are null and there are conflicts with this constraint. https://github.com/mgov88/gora/blob/GORA-663/gora-neo4j/src/test/resources/gora-neo4j-mapping.xml#L22 Is it correct this way?

Outreachy - Add a datastore for Neo4j in Apache Gora
Hi all. I am Gaby Ortiz and my initial application for the Outreach program was accepted today. I was checking out the projects list and this project seems to be a good fit for my knowledge background. I studied software engineering a couple years ago and in my final project at the University I worked with graph databases such as Jena TDB, Virtuoso and GraphDB for a Linked Data project. I was checking out Neo4j and the basic concepts are the same, then I would like to apply for this project. I have experience working with the Java programming language and related tools such as maven, gradle, testcontainers, etc. And I am familiar with NoSQL databases (especially graph-based). I was wondering which should be my next steps?. I saw a list of warm-up tasks in the Outreachy platform, how can I be assigned one of those tasks in order to get started with Apache Gora?. Do you have suggestions or guidelines that I should consider before applying for this project? I saw many communication channels in the project description: jira, github, wiki, mailing list, and personal emails of the mentors. I was wondering how should I contact you?. The Outreachy documentation says ".. contact the mentor on public community channels as much as possible." so I am writing to the public developers mailing list, is it ok with you?. Thanks, Gaby
