As written recently I have the the chance to rewrite the entire platform with a team of 6 programmers.
This time we want to do it the correct why. Instead of Thinking of features right away we are now thinking about the various stake holders for whom we are creating metalcon.
Of course being a fan of metal music I know pretty well what requirements a social network for metal music should fulfill to add value for me.
Running such a platform and being member of the In Legend team I also can think of various requirements from Musicians but I want to open the discussion and ask the musicians:

What do you expect from a social networking site and for what reasons would you use it?

We have already created a small list at:
https://github.com/renepickhardt/metalcon/wiki/requirementsBand
which I am sharing here and asking musicians to contribute to. Eather here in the comment section or via the github wiki. Thanks a lot

Self promotion

Bands want to advertise their music and get a lot of attation.

Music hosting

Bands often lack technical knowledge to host their music. Metalcon can provide them with the functionality to host promotional songs and also share the player on other websites and with other services.

Control

The worst that could happen to a band is that they spend a lot of effort building up their fan base on a social networking site like they did in the early 2000s and then the site becomes irrelevant. Similar problems hold with facebook where page owners nowadays have to pay money to get their message spread to everybody who liked the fan page.

Therefore a requirement for musicians is to keep control of their fan base that they have grown so far.

Contact with fans and Streetteam

Bands want contact to their most important fans and to people who can organize stuff for them. Heaving a streetteam is essential to the sucess of many bands. Using a social networking service can help the band to fulfill their goal

Privacy

Famous musicians want to use the band profil of a social networking site without revealing their private account.

Staying in contact with other industry players

Musicians might want to stay in contact with partners from

  • labels
  • booking agencies
  • promoters
  • photographers
  • video producers
  • music producers
  • venue owners

Sell products

Bands want the possibility to sell

  • Tickets
  • Merchandise
  • Music (MP3 and CD)

Booking

Bands want to get the opportunity to book gigs. Giving them the opportunity to get in contact with bookers will help them.

release Management

Bands often have a complete produced record. This should be shared with some players from the industry. In this process the music should be

  • hosted in the web
  • watermarked (to prevent leaking)
  • shared privately with selected partners
  • only be streamed from the web

Experiences on semantifying a Mediawiki for the biggest recource about Chinese rock music: rockinchina .com https://www.rene-pickhardt.de/experiences-on-semantifying-a-mediawiki-for-the-biggest-recource-about-chinese-rock-music-rockinchina-com/ https://www.rene-pickhardt.de/experiences-on-semantifying-a-mediawiki-for-the-biggest-recource-about-chinese-rock-music-rockinchina-com/#comments Mon, 07 Jan 2013 09:38:45 +0000 http://www.rene-pickhardt.de/?p=1486 During my trip in China I was visiting Beijing on two weekends and Maceau on another weekend. These trips have been mainly motivated to meet old friends. Especially the heads behind the biggest English resource of Chinese Rock music Rock in China who are Max-Leonhard von Schaper and the founder of the biggest Chinese Rock Print Magazin Yang Yu. After looking at their wiki which is pure gold in terms of content but consists mainly of plain text I introduced them the idea of putting semantics inside the project. While consulting them a little bit and pointing them to the right resources Max did basically the entire work (by taking a one month holiday from his job. Boy this is passion!).
I am very happy to anounce that the data of rock in china is published as linked open data and the process of semantifying the website is in great shape. In the following you can read about Max experiences doing the work. This is particularly interesting because Max has no scientific background in semantic technologies. So we can learn a lot on how to improve these technologies to be ready to be used by everybody:

To summarize, for a non-scientific greenhorn experimenting with semantic mediawiki and the semantic data principle in general, a good two months were required to bring our system to the point where it is today. As easy as it seems in the beginning, there is still a lot of manual coding and changing to be done as well as trial-and-error to understand how the new system is working.
Apart from the great learning experience and availability of our data in RDF format, our own website expanded in the process by ~20% of content pages (from 4000 to above 5000), adding over 10000 real property triplets and gaining an additional 300 thousand pageviews.
Lessons learnt in a comprised way:

  • DBPedia resources are to be linked with “resources” in the URI not with “page”
  • SMW requires the pre-fix “foaf:” or “mo:” or something else for EACH imported property
  • Check the Special:ExportRDF early to see if your properties work
  • Properties / Predicates , no difference with SMW
  • How to get data to freebase depends on the backlinks and sameas to other ontologies as well as entering data in semantic search engines
  • Forms for user data entry are very important!
  • As a non-scientific person without feedback I would not have been able to implement that.
  • DBPedia and music ontology ARE not interlinked with SAMEAS (as checked on sameas.org).
  • Factbox only works with the standard skin (monoskin). For other skins one has to include it in the PHP code oneself.

Main article

The online wiki Rock in China has been online for a number of years and focusses on Chinese underground music. Prior to starting implementing Semantic Mediawikia our wiki had roughly 4000 content pages with over 1800 artists and 900 records. We used a number of templates for bands, CDs, venues and labels, but apart from using numerous categories and the DynamicPageList extension for a few joints, we were not able to tangibly use the available data.
DPL example for JOINT between two Wikipedia Categories:

<DynamicPageList>
category = Metal Artists
category = Beijing Artists
mode     = ricstyle
order  = ascending
</DynamicPageList>

Results of a simple mashup query: display venues in beijing on a Google Map

After having had an interesting discussion with Rene on the benefits of semantic data and Open Linked Data, we decided to go Semantic. As total greenhorns to the field and with only limited programming skills timely available, we started off googeling the respective key terms and quickly enough came to the websites of the Music Ontology and the Semantic Mediawiki, which we decided to install.
Being an electrical engineer with basic IT backgrounds and many years of working on the web in PHP, HTML, Joomla or Mediawiki, it was still a challenge to get used to the new semantic way of talking and understanding the principles behind. Not so much because there might not be enough tutorials or data information out in the web, but because the guiding principle is somewhere but not where I was looking. Without the help of Rene and several feedback discussions I don’t it would have been possible for us to implement this system within the month that it took us.
Our first difficulty (after getting the extension on our FTP server) was to upgrade our existing Mediawiki from version 1.16 to version 1.19. An upgrade that used up the better part of two days, including updating all other extensions as well (with five of them not working anymore at all, as they are not being further developed) and finally getting our first Semantic Property running.
Upon starting of implementing the semantic approach, I read a lot online on the various ontologies available and intensively checked the Music Ontology. However Music Ontology is by far the wrong use case for our wiki, as Music Ontology is going more into the musical creation process and Rock in China is describing the scene developments. All our implementations were tracked on the wiki page Rock in China – Semantic Approach for other team members to understand the current process and to document workarounds and problems.
Our first test class had been Venue, a category in which we had 40 – 50 live houses of China with various level of data depth that we could put into the following template SemanticVenue:

{{SemanticVenue
|Image=
|ImageDescription=
|City=
|Address=
|Phone=
|Opened=
|Closed=
|GeoLocation=
}}

As can be seen from the above template both predicates (City) and properties (Opened) are being proposed for the semantic class VENUE. Semantic Mediawiki is implementing this decisive difference in a very user-friendly way by setting the TYPE of each SMW property to either PAGE or something else. As good as this is, it somehow confuses if one is talking with someone else about the semantic concept in principle.
A major problem had been the implementation of external ontologies which was not sufficiently documented on the semantic mediawiki page, most probably due to a change in versioning. Especially the cross-referencing to the URI was a major problem. As per Semantic Mediawiki documentation, aliases would be allowed, however with trial and error, it was revealed that only a property with a domain prefix, e.g. foaf:phone or owl:sameas would be correctly recognized. We used the Special:RDFExport function to find most of these errors, everytime our URI referencing was wrong, we would get a parser function error.
First, the wrong way for the following two wiki pages:

  • Mediawiki:smw_import_mo
  • Property:genre

Mediawiki:smw_import_mo:

http://purl.org/ontology/mo/ |[http://musicontology.com/ Music Ontology Specification]
activity_end|Type:Date
activity_start|Type:Date
MusicArtist|Category
genre|Type:Page
Genre|Category
track|Type:String
media_type|Type:String
publisher|Type:Page
origin|Type:Page
lyrics|Type:Text
free_download|Type:URL

Property:genre:

[[Has type::Page]][[Imported from::mo:genre]]

And now the correct way how it should be actually implemented to work:
Mediawiki:smw_import_mo:

http://purl.org/ontology/mo/|[http://musicontology.com/ Music Ontology Specification]
activity_end|Type:Date
activity_start|Type:Date
MusicArtist|Category
genre|Type:Page
Genre|Category
track|Type:String
media_type|Type:String
publisher|Type:Page
origin|Type:Page
lyrics|Type:Text
free_download|Type:URL

Property:mo:genre:

[[Has type::Page]][[Imported from::mo:genre]]

The ontology with most problems was the dbpedia, which documentation did not tell us what the correct URI was. Luckily the mailing list provided support and we got to know which the correct URI was:

http://www.dbpedia.org/ontology/

Being provided that, we were able to implement a number of semantic properties for a number of classes and start updating our wiki pages to get the data on our semantic database.
To utilize semantic properties within a wiki, there is a number of extensions available, such as Semantic Forms, Semantic Result Formats and Semantic Maps. The benefits we were able to gain were tremendous. For example the original JOINT query that we had been running at the beginning of the blog post with DPL was now able to be utilized with the following ASK query:

{{#ask: [[Category:Artists]] [[mo:origin:Beijing]]
|format=list
}}

However with the major benefit that the <references/> extension would NOT be broken after setting the inline query within a page. Dynamic Page List breaks the <references/>, rendering a lot of information lost. Other examples of how we benefitted from semantics is that previously we were only able to use Categories and read information of joining one or two categories, e.g. Artist pages that were both categorized as BEIJING artists and METAL artists. However now, with semantic properties, we had a lot of more data to play around with and could create mashup pages such as ROCK or Category:Records on which we were able to implement random videos from any ROCK artists or on which we were able to include a TIMELINE view of released records.

Mashup Page with a suitable video

With the help of the mailing list of Semantic Mediawiki itself (which was of great help when we were struggling) we implemented inline queries using templates to avoid later data changes on multiple pages. That step taken, the basic semantic structures were set up at our wiki and it was time for our next step: Bringing the semantic data of our wiki to others!
And here we are, asking ourselves: How will Freebase or DBpedia actually find our data? How will they include it? Discussing this with Rene a few structural problems became apparent. Being used to work with Wikipedia we usually set the property same:

Owl:sameas (or sameas)

On various of our pages directly to Wikipedia pages.
However we learnt that the property

foaf:primaryTopic

is a much better and accurate property for this. The sameas property should be used for semantic RDF pages, i.e. the respective DBPedia RESOURCE page (not the PAGE page). Luckily we already implemented the sameas property mostly in templates, so it was easy enough to exchange the properties.
Having figured out this issue, we checked out both the freebase page as well as other pages, such as DBpedia or musicbrainz, but there seems to be no “submit RDF” form. Hence we decided that the best way for getting recognized in the Semantic Web is to include more links to other RDF resources, e.g. for our Category:Artists we set sameas links to dbpedia and music ontology. For dbpedia we linked to the class and for music ontology to the URI for the class.
Note on the side here, when checking on sameas.org, it seems that music ontology is NOT cross-linked to dbpedia so far.
Following the recommendations set forth at Sindice, we changed our robots.txt to include our semantic sitemap(s):

Sitemap: http://www.music-china.org/wiki/index.php?title=Special:RecentChanges&feed=atom
Sitemap: http://www.rockinchina.com/wiki/index.php?title=Special:RecentChanges&feed=atom

Going the next step we analyzed how we can include external data on our SMW, e.g. from musicbrainz or from youtube. Being a music-oriented page especially Youtube was of particular interest for us. We found the SMW extension External Data that we could use to connect with the Google API:

{{#get_web_data:
url=https://www.googleapis.com/youtube/v3/search?part=snippet&q=carsick+cars&topicId=%2Fm%2F03cmgbv&type=video&key=Googlev3API&maxResults=50
|format=JSON
|data= videoId=videoId,title=title
}}

And

{{#for_external_table:
{{Youtube|ID={{{videoId}}}|title={{{title}}} }}<br/>
{{{videoId}}} and {{{title}}}<br/>
}}

See our internal TESTPAGE for the live example.
Youtube is using its in-house Freebase ID system to generate auto-channels filled with official music videos of bands and singers. The Freebase ID can be found on the individual freebase RESOURCE page after pressing the EDIT button. Alternatively one could use the Google API to receive the ID, but would need a Youtube internal HC ID prior to that. Easy implementation for our wiki: Include the FreebaseID as semantic property on artist pages within our definitions template:

{{Definitions
|wikipedia=
|dbpedia=
|freebase=
|freebaseID=
|musicbrainz=
|youtubeautochannel=
}}

Voila, with the additional SQL-based caching of request queries (e.g. JSON) our API load on Google is extremely low as well as increasing speed for loading a page at our wiki. Using this method we were able to increase our saved YOUTUBE id tags from the original 500 to way over 1000 within half a day.

A big variety of videos for an act like carsick cars is now available thanks to semantifying

With these structures in place it was time to inform the people in our community not only on the changes that have been made but also on the additional benefits and possibilities. We used our own blog as well as our Facebook page and Facebook group to spread the word.

Question by Filip Stilin (House on Mars): What do you think of Bandcamp? https://www.rene-pickhardt.de/question-by-filip-stilin-house-on-mars-what-do-you-think-of-bandcamp/ https://www.rene-pickhardt.de/question-by-filip-stilin-house-on-mars-what-do-you-think-of-bandcamp/#comments Sat, 21 Jan 2012 00:36:10 +0000 http://www.rene-pickhardt.de/?p=1037 Filip Stilin is the frontman of House on Mars a promesing young croation band (check out their music on bandcamp). He loves music and online marketing so he read my blog and sent me and email with a couple of interesting observations and questions. I got his permission to publish parts of his mail and answer the questions to a wider audiance in my blog.

Filip: Even though I wasn’t agreeing with your Facebook skepticism in the beginning, I realized that I was overestimating Facebook in its promotion role. I’ve been creating extremely successful, targeted (extremely low budget though – just 5 or 10 euros at a time) campaigns for my band on Facebook.

Results?

Even though I managed to inflate the number of fans (with 12 fans/1 euro average), the interaction stayed the same. These campaigns aren’t entirely useless, though – having this number of fans or more looks nice in a smaller Croatian market and can help in booking bigger shows (thus getting to more fans)..but still dissappointing. I won’t campaign until we release a website/album/have something to sell.

Rene: I like your observation. The first was that gaining these paid likes does not really increase interactions and increase your reach. As I am saying to the In Legend guys all the time: “Money invested in facebook or even effort in facebook reach is not the best way to increase one’s reach” I am very glad that you came to the same conclusion and shared your insights!
Secondly I partially agree with the effect of large fan numbers while booking gigs. It certainly looks good to business partners like bookers, labels, distributers,… if your social media numbers burst. But again I would say the price is too high. With 1 Euro / 12 fans you would need to invest 1000 Euro for 12’000 fans an 12’000 isn’t even skyhigh (well I don’t know about croation standards). But as we know only a very small fraction of these 12’000 fans would actually become real fans and start interacting with you. All this for getting a gig! I guess this money could much better be invested in a high quality video which especially for a young band is a very good investment. With the video in combination with smart music downloads you will be able to increase your reach. Maybe not to 12’000 fans but still to a solid number of real fans that actually come to your concert because they really care! In this way your social media fancount (especially facebook) will also grow.

Filip: Question1 – sharing music!
About the thesis of providing music only on the band site – I think it’s hard for someone to become our fan if there is no music on Facebook. Choosing one song for preview and directing a fan to .com might work, but they are attracting entirely different audiences – think poppy indie rock vs. oriental, modern metal ballad. Is it okay to let this promo run free and spread like wildfire until the album release? Or should I provide 2/3 of songs for free, and ask for a mail adress for the 3rd one? This might be a good model.

Rene: I agree with what you say. At the time of writing the blog post you are referring too I wasn’t aware of the existing facebook music apps. The important thing is getting a sustainable contact to the person interested in your music. This is achieved ultimately by his email adress. But your question is very important. Of course you have to give people a bait. This could be

  1. snippets
  2. entire song(s) on streeming
  3. a music video (In legend offers downloads under every music video)
  4. a free download (without registration)

and I really don’t know where to set the boarder.
In the beginning times of In Legend we had 3 songs for streaming on myspace and 4 songs on the ep for download in exchange of an email adress. That turned out to be a good solution. People who liked the first songs where curious to download them together with one additional song. So I guess a 2/3 split would work as well. I will just warn you. Asking people for their mail address scares 4 of 5 people away. But hey at least you get the adresses of your fans that are really willing to give something for the music!
Now about the place where to make the connection. If you achive getting the fans mail adress via a smart Facebook music player or via download on your homepage I don’t care. Once people like your music (and chances are higher once you can talk to them frequently) they will also turn into facebook fans. So I recommend switching from rootmusic which you are using right now on your facebook profile to bandRX or Songpier since both services allow you to give access to your music in return of mail adresses. Songpier is a very new service but they also offer a cool mobile app (right now also without collecting mail adresses)
Here is a video about bandRX

Filip: Question2 – What do you think of Bandcamp?
I personally think it’s a great platform for selling music and there is an option of collecting mail adresses. The downside is that there is no valuable content that can be published, like blogs. It would be perfect if it was just a music-streaming, checkout widget on my site.

Rene: One of my Favourite (but retired) bands Jester’s Funeral have just published all their songs to bandcamp and have linked to their homepage and from the homepage to bandcamp. It is not quite the widged you are asking for but I guess this stays an option especially if you don’t bring the technical know how of programming a homepage that enables you to offer your music as a download in exchange of mail adresses.
There is only one thing that bothers me about bandcamp. They only let 200 fans per month download your music for free (email exchange) and offer a pay as much as you want option. From the money raised they keep 15% as a service charge. If you want more free downloads you have to buy them or have people pay for your music.
To some extend they offer a fair deal. It is a good service for a reasonable price. I as a programmer would just do it on my own have the full controll of my data and keep the 15% but I am pretty convinced that bandcamp should be a pretty good option for many musicians
I hope I could answer your questions to your satisfaction! Sorry that there isn’t always the clear black our white, right or wrong. Things are complex on the web but by reading your mail I am very convinced that you are asking the right questions which means that at least in online marketing you are far ahead of 95% of all musicians!
