Compare dependency graphs

Put two dependency graphs next to each other and read what the second one states differently from the first: the axioms it adds, removes or relates another way, and the default rules it adds, drops or changes, each with its legal basis, its status and a plain explanation. Nothing shown here is legal advice.

Swap the two

Japan default rules, version 2, against DALICC deontic dependency graph, version 2.

Axioms: 0 added, 0 removed, 0 changed. Default rules: 0 added, 3 removed, 0 changed.

What the second graph adds

Nothing: every statement of DALICC deontic dependency graph is in Japan default rules too.

What the second graph does not have

Default rules 3

Status
dalicc:moralRightsRestriction Moral rights restriction Not waivable Japan Copyright Act article 59: the moral rights of the author are exclusive to the author and inalienable, so a licence cannot transfer them Proposed
This rule adds nothing to a licence that says nothing about moral rights; it reports a finding when a licence permits the licensee to set them aside. Under the Copyright Act of Japan the moral rights of the author are exclusive to the author and inalienable, so a licence cannot transfer them. A person combining licences under this graph sees the finding beside a licence that claims to transfer or waive them; an agreement not to exercise them is common in Japan and its effect is decided case by case.
dalicc:sellCopy Sell copy Granted by default Japan Copyright Act article 26-2(2): the transfer right is exhausted once the original or a copy has been transferred with the authorisation of the rightholder. Cinematographic works fall under article 26 instead; the Supreme Court held the distribution right in game software exhausted after the first lawful transfer (25 April 2002) Proposed
A licence that says nothing about reselling a copy is read as allowing a copy that was sold to be sold on. The Copyright Act of Japan exhausts the transfer right once the original or a copy has been transferred with the authorisation of the rightholder. Combining a licence that is silent about it with one that prohibits it shows a conflict marked as coming from this rule.
dalicc:textAndDataMining Text and data mining Granted by default Japan Copyright Act article 30-4: a work may be exploited, to the extent considered necessary, where the purpose is not to enjoy the thoughts or sentiments expressed in it, including data analysis, unless this would unreasonably prejudice the interests of the copyright owner in light of the nature or purpose of the work or the circumstances of its exploitation Proposed
A licence that says nothing about text and data mining is read as allowing it. Article 30-4 of the Copyright Act of Japan lets a work be exploited to the extent considered necessary where the purpose is not to enjoy the thoughts or sentiments it expresses, which covers data analysis, except where the use would unreasonably prejudice the interests of the copyright owner. Combining a licence that is silent about it with one that prohibits it shows a conflict marked as coming from this rule.

What both have in a different form

Nothing: no statement is in both graphs in a different form.
