Browsing
the web, one can find statements like this: “Because aesthetics and visual
design aren’t part of the ESEF requirements, design details are often
overlooked in the conversion process of PDF files and the transformation will
eliminate all the benefits of a beautifully designed report.”
Is really ESEF a conversion of nice-looking PDF files?
PDF and
HTML are two different technologies and experts could spend enormous amounts of
time explaining the pros and cons based on their expertise and preferences.
In
summary, it can be said that PDF is just a file format used primarily to be
printed, archived, or integrated into a pre-press production line. The
visualization of the document is frozen and non-adaptable while HTML is web
format, which can be created with a simple text editor and adapts to all types
of visualization.
In addition,
ESEF is about iXBRL which takes the HTML standard that is used to power the
world’s web pages and embeds extra “tags” into it. It gives meaning to the
figures and statements in a format that can be understood by a
computer.
Preparers and users
Should
preparers focus on their financial statements design? Of course, and iXBRL
allows preparers to retain full control over the presentation of their report.
This includes the use of graphics and photos.
Should
they be concerned on how they will look like if printed: this is what PDF technology
has developed for years now, involving the cost of highly paid design agencies?
Or
should they be more concerned how they will be used with modern technology?
Users
will never print the PDF files. The printing remains in the hands of the
company that publishes the document.
The UK
Government has recognized “that people read differently on the web than they do on paper. This means
that the best approach when writing for the web is different from writing for
print and concluded that it is really important to create content that is
clear, concise, structured appropriately and focused on meeting the user need.
A PDF document that was created for offline use will not suit the context of
the web and is likely to result in a poor user experience.”
In
addition, as XBRL International writes: “Working with iXBRL data is not just
about exploring reports using a web browser. Valid iXBRL reports can be
loaded into any compliant processor, and the data within them can be
consumed by analytics engines, loaded into databases for querying, or
processed into new reports. All this can be done whilst retaining links
back to the information as it was originally reported and presented.
ESEF is not about conversion of PDF to html
Considering
that ESEF is just a conversion of nice-looking PDF documents to nice looking html
documents is reducing ESEF to a change in format. Also considering ESEF as another
regulatory mandate is not taking ESEF for what it is. ESEF is about structuring content: rendering
the information more accessible, understandable, and usable for comparisons and
analysis.
ESEF is
all about the tags that are inside and are not viewed in a printed form. As an
example, and barely scratching the surface of what is possible using iXBRL
data, it is possible to automatically search company’s accounts to find disclosures
relating to a particular accounting standard.
ESEF is
limited today by ESMA to the tagging of primary financial statements but the
benefits of combining human-readable and machine-readable information can
assist many domains in making the transition away from inefficient manual
processes and to the use of artificial intelligence. Other reporting systems require
more granular information to be tagged, together with textual information. This
opens the field of much wider digitalization of information as, already
prepared and tested, all environmental and societal information which is more
and more used in the assessment of an enterprise operations.
The
future is therefore to produce more accessible, precise and structured web
information and it is time to make systems evolve to prepare such information,
rather than trying to reproduce and transform old processes that were made for paper based technologies.
