Usage for description of software features

When adding software applications I found different uses of properties to describe the aim and features. In some cases manifestation of (P1557) is used to describe the implementation of a software package (e.g. ontology editor (Q453843) or FileZilla (Q300662). Others use implementation of (P4428) (e.g.Mozilla Thunderbird (Q483604) or Microsoft Outlook (Q80911)). I would rather use implementation of (P4428) to describe features and aim of the software. I would be interested in the communities feedback or a link to best practices. --Katjos (talk) 14:13, 10 March 2018 (UTC)
