We do not have a current example of what the value would look like for attributes with multiple tags. So for attributes that have multiple tags, how are the tags separated in the meta.tags property?
In GoodData the tags are actually separaye by a space. So multiple tags are multiple words separated by a space and the whole meta.tags is actually not an array but a string.

I have a data set containing millions of items collected from many disparate sources. Each item contains a list of anywhere from fifty to a thousand attributes. The specific attributes available vary greatly from item to item.
I am looking for the best way to find the most similar items to a given target item of members in the set. (I obviously want to accomplish this without doing a brute-force comparison against all of the items in the set.)
I would like to use something like Locality Sensitive Hashing with MinHash. However, if the target item has 50 attributes and a likely matching item within the larger data set has 200, MinHash will consider these as dissimilar even if the item with 200 attributes contains all of the attributes of the target item.
What are the best techniques or algorithms to use to compare items with dissimilar numbers of attributes?
I am in the process of data exploration and have given (varied) XML in SQL Server. There are about 1,500 records with a header record, load date and RAW_XML column. In that XML column there are varying records; x num of elements, within those elements, x num of attributes. Within each record there are not fixed num of elements; there are some repeated elements and in other records new elements. If there are repeated elements in a record there can be a few attributes to that element and at other times many attributes to it.
I have consulted many XML related articles, methods in querying etc. but these demonstrate doing so by fixed elements and attributes. I am not sure how to do this with such varied data. Is there an exploratory method that I have not considered here?
I am creating a site for a card game and I have a problem with the search function.
I want to allow users to search for cards that match any number of options for a given field (e.g. the cards can be 1 of six different factions and I have a multi select box that allows users to select multiple factions to match). If the card can only be one of the options then I can simply build the query using the 'IN' sql operator and that works fine.
I run into a problem when the card has multiple subtypes in the database. Right now I am storing the subtypes as a comma separated list in a single field and I want to use the '&&' operator to compare the 2 sets but that is an array operator and the data in the table apparently isn't stored as an array so it isn't working.
Is there a way to do this?
Don't use comma-separated lists to store your card attributes; that's not going to work.
Either create new columns in your Cards table for each attribute, or join another table that contains the attributes in a one-to-many relationship with your Cards table.
I am working on xml in openerp. I am creating access right for an specific user. I want to know if is possible to add more than one group in the groups tag adding a comma, semicolon or some char?
I've tried this but it is not working:
groups="x_stock_picking.confirm_transfer, stock.group_stock_user"
is that possible ?
You have to separate them with coma without any spaces.
groups="x_stock_picking.confirm_transfer,stock.group_stock_user"
Spawnable Field sets, bunches of them - all on a single list item. Can it be done?
In our particular instance, we're creating a look-up field and a couple of text fields that relate to the item.
The user needs to be able to generate those field sets multiple times in the same item, to look up a distinct value, and also enter information about that look-up in the other text fields.
