Informační systém Datových schránek je významným informačním systémem státní infrastruktury. Návrhu takové informačního systému je nutné věnovat patřičnou péči i vzhledem k tomu, že pokud by se v návrhu později objevila trhlina, mohla by mít nedozírné následky na všechny uživatele. Trhlina, o které budeme pojednávat, se týká způsobu zasílání některých datových zpráv obsahujících přílohy ve formátu PDF. Některé z těchto příloh nemusí být příjemci používajícími výchozí internetový prohlížeč Safari na operačním systému OS X schopni správně otevřít. Článek tuto situaci analyzuje a dává odpověď na otázku, kdy bude příloha ve formátu PDF otevřena správně a kdy nikoliv.

On the Legibility of Data Message PDF Attachments on the OS X Platform

The Data Message Information System is a remarkable information system of the state infrastructure. Design of an information system of such importance should be done with much care also due to fact that if a design flaw appeared later, it could have severe impacts at the users. A flaw that will be discussed in this paper applies to a data message sending process of messages containing PDF attachments. Users with the default Safari web browser on OS X do not need to be always able to open such attachments. The paper analyses the situation and gives an answer to a question when will a PDF attachment be opened correctly and when not.

Keywords: Data Message, Data Mailbox, DMIS, PDF, OS X, Safari
