avattuja

Could you clarify what "avattuja" refers to? In Finnish, "avattuja" is a participial form meaning "opened" or "unveiled," but it could also be a proper noun (a title, place, artist name, etc.). Do you want a linguistic/grammatical article about the word, or a neutral encyclopedic entry about a specific topic named "avattuja" (if it is a band, book, location, concept, etc.)? Any context or background will help me produce a concise, wiki-style article under 300 words.
