Creators of original content are to be given more rights over their work when it is shared online following the signing into Irish law of an EU Directive.
The EU's Copyright Directive, which comes into effect today, updates Irish copyright law to make it more relevant for the digital age.
The new law will strengthen the rights and protections afforded to various categories of copyright holders, including journalists and authors, when their work is shared online.
Online service providers will also have to negotiate agreements with media organisations to allow sharing of articles.
"From now on in Ireland, press publishers such as newspapers have a new legal right in relation to the use of their content by online service providers," Tánaiste and Minister for Enterprise Leo Varadkar explained.
"In the absence of an agreement with publishers, online platforms will not be permitted to make use of their work, though they will continue to be able to use hyperlinks or very short extracts," he added.
The Tánaiste said it would be up to the publisher and the online provider to negotiate an agreement.
"People want to keep getting their news from social media so there is a clear, mutual benefit for both parties in reaching these agreements," he said.
The law also gives authors and performers the right to negotiate appropriate and proportionate remuneration when making an agreement to transfer the rights to their work.
They are also to be granted greater transparency about how their work is used as well as a right to take back their rights when their works are not being used.
"As society continues to transition on a greater digital journey, it is important that the impact of technological advances and increased digitalisation will be fair and balanced for all those copyright holders, publishers and platforms involved in making available original and creative works across Ireland," Minister of State Damien English said of the new law.
