When preserving a data its a material that is use-able all the time, however when a data is curated its stored in safety for future use if other sources get deleted or is lost, and when we aggregate data is when we combine all the observations of all sources and make a summary out of it. I think the challenges is not only to find the main source but to also see who can use that data, and when summarizing a group of sources one must make sure to keep the important subjects in the summary, sometimes an important sentence or name can be forgotten.
Well when a data is put online anyone can access it, but sometimes when searching we may not find the reliable true source, however when something goes online such as a history data it should be free and open to public, but lets say if it’s from a book the author would not like his work to be out free of charge. I think the resolution can come from the website that is providing that data, they can simply pay the source and not charge the users, which is impossible to do so.
I would start with a family tree, write down my family members as much as I know them, and then asking my parents and grandparents about how much information they have about distant relatives. I would share names and relations, age, place of birth and where they live now. By just a click on each persons name they can see the important dates and informations about their life(birth, marriage, children, if ever immigrated) a sentence for each important event as long as it doesn’t get to personal. I would write a brief history about how the family came to be and how we got our last name, if we, in time of history have ever been connected to anyone famous(royalty, inventor, painter,etc…). I would make it easy for members of the family to contribute to the collection, create a username and password, so anytime someone finds a new information about the past or has something new to add(birth, marriage, death), easily go online and add it, instead of telling me to do it when I have a free time.
Any website that they know their sources are reliable, if we’re talking about modern history, any website that they know the journalist name or the news website thats giving that information. If it’s about the older history dating back to thousands of years ago, they should read about the archeologist who provided that information and the person who wrote about that archeologist, see where the sources came from and how accurate they are. That last part I cannot really say how a google search or any search engine in particular can preserve these information’s or based on what interface people can easily pull it up. Maybe aside from searching the name of the historical figure, adding the event they’re looking for, and that website containing that subject pop-up the preserved website as first results.
