When selecting resources try to locate authentic Indigenous Knowledge, and make sure you are treating it in a respectful manner. Often there are protocols around the use of Indigenous Knowledge, even when it has been (via permission or not) posted online. 

You should always try to obtain permission for use, including cultural materials or practices such as legends, stories, songs, designs, crests, photographs, audiovisual materials, and dances from affected individuals, artists, families, Elders, hereditary Chiefs, Band Councils, or Tribal Councils prior to use. 

Some Indigenous Knowledge resources may contain Traditional Knowledge Labels and the terms of those labels should be followed.
