Best method to store ordered list?

I'm looking for the optimal method for storing/retirieving  a list of items that i allow the user to sort using a php/js/html front end.

I have a "projects" table that is used to store name, dates, abstract, etc for a project. I also need to store information regarding a static list of relevant keywords. For instance a set of 10 keywords, each with a rank chosen by the user. I assume that i should use a m-m type set up with a linking table but am not sure regarding the optimal implementation. Should I create a "keywords" table, populate it with the words, then store the sort information with the linking table?

Hi,

I would create a keyword table - populate it with the words and the ranking then link it to the other table.

Hmmm, I don't think I can store the ranking info with the keywords table, as there will be many projects each with their own individual ranking of keywords.

What I was thinking was having the keywords table, then in the linking table have the "projectsid" and "keywordsid" column, then have another column called "rank" or something that would store the rank for that particular keyword as it relates to the project.

Does that make sense? It seems like there must be a better way.

Well if the rankings are dynamic - have a ranking table, a keyword table and a project table.  then have one table that links all three together.

Nevermind about the sample, I just realized I was being foolish to begin with, I only need two tables with a third join I can store the rank info in an extra column in the join table. thanks
